Well they shouldn't. UUIDs are for distributed systems. Generating keys client side? That's a distributed system.

I've had occasional uses for it in systems that aren't distributed at all. It's a handy property of UUIDs, if UUIDs are useful for a particular use case, I'm going to use them, what they're 'supposed' to be for is irrelevant.
