Compatibility with new ADR-028 address derivation mechanism

[larry0x]

Not a problem that needs to be addressed immediately, but I want to point this out here.

The latest version of ADR-028 (https://github.com/cosmos/cosmos-sdk/blob/main/docs/architecture/adr-028-public-key-addresses.md) suggests a new address derivation mechanism that results in 32-byte addresses, instead of the current bitcoin-style 20-byte ones.

as of cosmos-sdk v0.47.0-alpha1, this has not been implemented. But if this is implemented and new chains start adopting it, we will have a tricky situation where users will have two sets of addresses (even if these chains all use the 118 derivation path):

• legacy “short addresses”
• new “long addresses”

Short addresses will be used on chains running old versions of cosmos-sdk, and long addresses will be used on those with new versions.

I am wondering if Stargaze Names can be designed to support both address formats.
