There are counter-arguments to that, though. Maintaining a lot of
extensions with only one or two functions in them is a nuisance.
Having things installed by default is convenient for wanting to use
them. Maintaining contrib code so that it works whether or not the SQL
definitions have been updated via ALTER EXTENSION .. UPDATE takes some
work and thought, and sometimes we screw it up.
I don't find any position on this topic to be without merit.
