Yes, exactly. In 1.2.2 you will be able to use "revuid" to do the
same thing with a bit less prompting.

Trust is chained via user IDs, so if you have multiple user IDs, and a
person signed them all, if you revoke one it does not matter from the
perspective of that person. If the person only signed one user ID,
and you revoke that one, then the chain stops that that point.
