x-for-userid does not check local gpg database
e.g. keys-for-userid, sshfprs-for-userid
This means that I can't create a key and verify that it was successful, locally, before publishing it.
Even if this is "intended behaviour", the documentation (e.g. man page) should be updated to make it clear that the local database is NOT queried by these commands.
