There were also no compelling reasons why json should have been an
extension. The two situations are not at all comparable. In any case,
no author of this patch has proposed any solution to the casting
problems described with using the jsonb type with the new (and
existing) hstore operators. For that reason, I won't comment further
on this until I hear a more concrete proposal.

I suspect that it's going to be considered odd to have code in core
that considers compatibility with earlier versions of hstore, back
when it was an extension, with calling stub functions, for one thing.
Having hstore be almost but not quite in core may be seen as a
contortion. Is that really the conversation you'd prefer to have at
this late stage? In any case, as I say, if that's the patch that
Andres or Oleg or Teodor really want to submit, then by all means let
them submit it. I maintain that the *current* state of affairs, where
jsonb isn't sure if it's in core or is an extension will not fly.
