We've always done our best not to break user-defined datatypes without
need. uuid doesn't seem to need any hooks into the core system that
would make it any more likely to break than anything else.
Per previous discussion, the main problem with a uuid type is the
new-uuid generator function, which tends to involve a bunch of
not-so-portable assumptions and code. If we accept a uuid type in
either core or contrib, all of a sudden those portability issues are
our problem. I'd rather not deal with that.
I'd be willing to accept a core uuid type sans generator function,
but is that really all that useful?
