You're talking about the hash-based UUIDv3/v5? I haven't found examples of those being used, but I'm curious.
Using MD5 or 122 bits of a SHA1 hash seems questionable now that both algorithms have known collisions. Using 122 bits of a SHA2/3 seems pretty limited too. Maybe if you've got trusted inputs?
