No, you don't need any quirks: you just do an "insert_resource()" and
ignore the error return. If the (bogus) PnP resource clashes with the
(correct) hardware PCI resource, the insert will simply fail. No quirks
needed.

No they are not.

If one does just device enumeration, and the other does resource
registrations, then they ARE NOT similar animals at all. Don't claim that
they are.
