No, certainly not. If anything, PGXN being a first class citizen would 
allow for potentially removing code from core, since there would then be 
a first-class way for users to add it.

I was under the impression that a lot of that had moved to test, but 
yes, that's a consideration. That said, if local caching was added to 
pgxnclient I don't think it'd require much change to just pull those 
cases from PGXN instead of the core repo. Alternatively, they could be 
pulled from a git repo that's houses the source code for the official 
PGXN modules (or what PGXN calls a distribution).

Those kind of changes would actually help any extension author that 
wants to depend on another extension (namely, automatically pulling 
dependent extensions from PGXN). I have make targets that currently 
accomplish this. They'd be nicer with some additions to both extensions 
and PGXN, but IMHO they're workable right now.
