I'm okay going with the xxhash for now, though personally I think it wouldn't hurt to set the bits to pretend that it's an MD5 hash-based UUID (as opposed to e.g. a timestamp UUID). I could see some tools caring about whether it's a timestamp vs a hash, but I think it's less likely that they would care about the exact hashing algorithm used. (RFC 4122 only specifies representations for MD5 and SHA1 hashes, so we can't represent xxhash.)

Makes sense. Put back the bits to claim that this is MD5. Please take another look :)
