What do you mean? Are you talking about validation of UUIDs?

If you generate random bytes, which are unlikely to conform to the UUIDv4 spec, my guess is that most libraries will silently accept the id. That is, generating random bytes, will probably work just work.

But what libraries are you talking about? What is their purpose?
