I'm clearly in the camp of "you can add and depreciate (experimental) features all you like in minor versions, but you should only remove them in major versions" camp.

See the discussion on semver and experiments: https://github.com/semver/semver/issues/238

That's the rule for normal features, that would mean there is no meaningful difference between stable and experimental parts of an API.

Hyrum’s law. Rust mostly gets around this by requiring you run the nightly compiler and library in addition to explicitly opting into experimental pieces.
