But that is irrelevant.

If we have registered them in the resource tree, then PnP must ignore 
them.

The fact is, this is not about being enabled or disabled. This is about 
the PnP tree containing resources that we already parsed from the PCI 
stuff, and once we've seen them as PCI resources, there's not really 
anything valuable in the PnP information.
