Audit experimental APIs (WP 5.6)

[tellthemachines]

This issue lists the experimental APIs in the editor, to help decide whether any of them can be made stable before 5.6.

I used @jorgefilipecosta's snippet to collect everything exposed via the wp global, and then searched the codebase for props and added in all I found.

There's also a bunch of __experimental stuff in the annotations package that I left out because it's been there a while and wasn't mentioned in API audits for the previous releases. Would love to know more about this if anyone has the history!

__experimentalRichText should be skipped for now :)

👋 Haii! Recently the InputControl (component) was improvement by @stokesman. (A great fix by the way!) However, we're unsure if it may have any side-effects. In theory it really shouldn't, but I'd feel better if we waited a bit to see if anything surfaces.

Because of that, I'd vote to skip the following:

Components

__experimentalBoxControl
__experimentalInputControl
__experimentalNumberControl
__experimentalUnitControl

Block Preview

__experimentalPadding

based on my experience (https://wordpress.slack.com/archives/C02QB2JS7/p1601634548288000, requires registration) with __experimentalLinkControl that one still needs some polish.

Just looking at the ones I've know from reviewing or adding myself:

Block Navigation
The following are all used in Block Navigation (now called List View):

• __experimentalBlockNavigationBlockFill, __experimentalBlockNavigationEditor - This feature didn't really go anywhere. I'm proposing to remove it in WIP: List View drag and drop optimizations #25069, I may split that PR up into smaller easier to review parts (cc @adamziel)
• __experimentalBlockNavigationTree - this probably won't be mature enough for 5.6, still quite a few ongoing discussions, and a proposal to rename all the BlockNavigation components to ListView anyway.
• __experimentalTreeGrid, __experimentalTreeGridCell, __experimentalTreeGridItem, __experimentalTreeGridRow - this is also used in block navigation, so not mature enough and potentially some parts will be replaced by reakit components.
• __experimentalFeatures - This is more of a feature flag, and won't become stable. (cc @adamziel)

Block API

• __experimentalGetAccessibleBlockLabel, __experimentalGetBlockLabel - I'm not sure what the plan is for these, the discussion stalled. Definitely not mature enough to stabilize.

Selectors

• __experimentalGetAllowedBlocks - this was added to support the inserter automatically inserting the block when only one block is allowed. I think it could be renamed to be more consistent and stabilized. (cc @draganescu)

This issue lists the experimental APIs in the editor, to help decide whether any of them can be made stable before 5.6.

👋 @tellthemachines, should we also add the __unstableIsEditorReady to the list?

[tellthemachines]

@WunderBart I purposefully left out everything marked __unstable as my understanding is that those APIs are not intended to be made public at any point.
