That makes sense.

The obvious thing to do is set a package property (or something
equivalent) that says it was found as a dependency.  The danger there is
that if something is first found as a dependency and then found
explicitly, it will be supressed.  We could minimise that by also
checking that the TYPE and PURPOSE package properties were not set.
