Has this behaviour been carried through into GRANT and REVOKE? If the
object is transparency for local users, it should be possible in
database "test" to say "GRANT ... TO fred" and have "fred" understood as
"fred(at)test".

If that is the case, then I will support the current position.

It follows from the objective of transparency that, when reporting a
user name, local users should be reported without the database suffix,
i.e., "fred" not "fred(at)test". Global users should be reported with the
trailing "@". This should cause no problem, because we have no
cross-database communication; it should be impossible for "george(at)dummy"
to have any connection with database "test".
