I would imagine that doc fixes would be gratefully accepted. Or if
they are rejected, that rejection would be confirmation that the
support is intended as an implementation detail (and a fix to the
documentation to explicitly state that would be reasonable).

Personally, I'd expect that the intention is that you can rely on it.
