It would be too late once we are in GA, and we are not yet in GA. At
this point I think that this should be Peter's call.

I am not in his shoes, still I suspect like you that we may have not
seen the end of it yet. If we're confident enough that we can fix
anything, that's fine as a response to me, but discussions are also
involving how available extensions are seen at catalog level. This
bit is concerning for me, but I'm also of a pessimistic nature.
