I agree with this. Though the restriction is not documented anywhere: I
am happy to add some explanatory notes though.

It does not need to be documented because that is a generally accepted rune, not something specific to this project. Interfaces should not change out of the blue. If a change must be made there are mechanisms (deprecation warnings, etc) that can be used to tell people about impending changes, and they're usually employed for 2 releases.
