Note: the final touches are not in place for this PR but I assume people can check their boxes based on the whole and assuming comments on this PR will get resolved.

I propose that we stabilize the MSRV-aware resolver.

Offer an opt-in config for preferring MSRV-compatible packages over those that are incompatible, regardless of version
Packages without an MSRV are always considered compatible
If no MSRV is defined, fallback to the current toolchain's version
Small tweaks in the algorithm are allowed as changes in the algorithm won't cause changes in lockfiles
This only applies to local lockfile generation and not to cargo install

This includes stabilizing

cargo generate-lockfile --ignore-rust-version
cargo update --ignore-rust-version

This does not include stabilizing

edition = "2024"
resolver = "3"
Features around the resolver that are meant to support MSRV workflows (e.g. --update-rust-version flag)

Deviations from the RFC

Instead of the MSRV being the lowest among the workspace's MSRVs, we prioritze packages based on how many MSRVs from the workspace they are compatible with
- We only fallback to the current toolchain's version if no MSRV is set, rather than treating that as the MSRV for those packages

I had considered proposing we have this cover cargo install

When viewed only as a config and keeping in mind that cargo install only reads from the user config (and so wouldn't be affected by the current repo's config), it sounds reasonable on the surface
However, people setting something in their config for cargo install would affect any repo that doesn't have its own config. Really, cargo install does need its own [install.resolver] table.
This also gets weirder when it comes to resolver = "3" as we'd need to describe that as conditional

This was stabilized in 1.83 in #.

This was stabilized in 1.83 in [#14639](https://github.com/rust-lang/cargo/pull/14639).

BTW, do you plan not to move anything to "Stabilized" section until every feature is implemented? Should we move just these two stabilized feature under independent h2 headings, which won't break link validity?

Hadn't really thought that through. Its a question of whether the stable section is documenting features or flags. Overall, I don't have a strong preference.

I am slightly towards moving them, but not going to block this PR for that reason.

As its already that way for some parts, let's handle the decision separately

[Stabilize MSRV-aware resolver config] (rust-lang/cargo#14639) - [Stabilize resolver v3] (rust-lang/cargo#14754) Rustdoc ------- - [rustdoc-search: improve type-driven search] (rust-lang/rust#127589) Compatibility Notes ------------------- - [Enable by default the `LSX` target feature for LoongArch Linux targets] (rust-lang/rust#132140) - [The unstable `-Zprofile` flag ("gcov-style" coverage instrumentation) has been removed.](rust-lang/rust#131829) This does not affect the stable flags for coverage instrumentation (`-Cinstrument-coverage`) and profile-guided optimization (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and remain available. - Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition] (rust-lang/compiler-team#607) [plan](rust-lang/compiler-team#695) for this target following [the introduction of `wasm32-wasip1`] (rust-lang/rust#120468) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`] (rust-lang/rust#126662) introduced in Rust 1.81 are now gone as well as the target is removed. - [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases] (rust-lang/rust#130635 (comment)) - [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).] (rust-lang/rust#130443 (comment)) - The `wasm32-unknown-emscripten` target's binary release of the standard library is now [built with the latest emsdk 3.1.68] (rust-lang/rust#131533), which fixes an ABI-incompatibility with Emscripten >= 3.1.42. If you are locally using a version of emsdk with an incompatible ABI (e.g. before 3.1.42 or a future one), you should build your code with `-Zbuild-std` to ensure that `std` uses the correct ABI. - [Declaring functions with a calling convention not supported on the current target now triggers a hard error] (rust-lang/rust#129935) - [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues] (rust-lang/rust#130654)
