Your logic is so flawed that it's scary.

Your logic is "I _can_ do it this way, thus everybody else must do it this
way". Where the _hell_ is the logic there?

I pointed out a _fact_: there are PCI bridges that bridge more than 3
resources. Argue with that until you turn blue in the face, I don't care.
I'm not talking about theory, I'm talking about bridges that I _have_ in
my machines, and that may have been set up by the firmware.

The fact that you could have built hardware and firmware that didn't have
more than three resources is _immaterial_, since it has nothing to do with
the realities of today.
