I'm completely not in favor of that.  We have spent man-years upon
man-years on making Postgres an extensible system.  If we can't actually
*use* the extension features then that was all a waste of effort.

If anything I'd rather see us looking at what parts of the current core
system could be pushed out to extensions.  The geometric types are a
pretty obvious candidate, for example.

Yeah, and it's a reasonable argument.  Even if it's not a reasonable
argument, you won't win any friends from the other side of the fence
by taking away their ability to choose.
