That's kinda short-sighted. You're assuming that the only place you'll
want to generate UUIDs is outside the database. What about a stored
procedure that's adding data to the database? How about populating a
table via a SELECT INTO? There's any number of cases where you'd want to
generate a UUID inside the database.

It's not about access to a library, it's about how do you get to that
library from inside the database, which may not be very easy.
You may not care for that convenience, but I certainly would.
