This doesn’t make sense. If you’re going to generate a new key if the user doesn’t exist then you’re creating a new user anyway, so there’s no hidden information. Unless you mean that the system should return a bogus id instead of a status 40X when the user doesn’t exist, which makes even less sense. ID generation should usually only happen when creating new assets, so it should be as fast as possible.
