The only counter argument given is that this will prevent people from
being able to use extensions because they A: can't or won't install
contrib packages or B: are too stupid or lazy to type 'create
extension json'.  Note I'm discussing 'in core extension vs in core
built in'.  'out of core extension' loosely translates to 'can't be
used by the vast majority of systems.

Most corporate IT departments (including mine) have a policy of only
installing packages through the operating system packaging to simplify
management of deploying updates.  Really strict companies might not
even allow anything but packages supplied by a vendor like redhat
(which in practice keeps you some versions back from the latest).
Now, if some crappy hosting company blocks contrib I don't believe at
all that this should drive our project management decisions.

Postgresql is both a database and increasingly a development language
platform.  Most good stacks have a system (cpan, npm, etgc)  to manage
the scope of the installed runtime and it's a routine and expected
exercise to leverage that system.
