I thought you always said that the local keyring is not trusted.
Further, if the user ever refreshes the key from the key server, then
the other user ids will be imported.
(Note: for something like the automated encryption scheme  that
uses keys retrieved via WKD as proof of basic validity, we need to
track whether the user id, not the key, was retreived via WKD!)
