I think at the time, making something an add-on would have placed an
excessive burden on potential users. The claim was that most UUIDs are
generated by applications, so having the type in core would be
important, but having the generation functions not so much.
That said, there have been several proposals over the years to move a
few things out of the core into add-ons, and now that extension support
exists, we could potentially reopen that discussion.
