IMO, we could release it as an experimental feature and prominently
announce that API changes might happen between major versions of Emacs.
That would give us room to make even backward-incompatible changes,
if/when necessary.

I don't necessarily advocate this; I only want to point out that this is
an option.

(Of course, this would not preclude trying to make it as stable as
possible before Emacs 28.)
