If I hadn't been using RFC 4122 UUIDs, I wouldn't have had any reserved bits to work with. There are a bunch of places in this system that restricted the report ID to be a hex string of length 32 that would have needed updating if I switched to a different format.

There's also no functional difference between a v4 UUID and a v5 UUID with fixed namespace and random bits for the name portion, so I disagree what I'm doing is no longer RFC 4122 compliant.

It's lucky I used RFC 4122 UUIDs in the first place, that I could take advantage of the designers foresight to set aside some extra bits.
