Almost all of them. Consider a bridge.

in v2, it means that in the init function, the CMD register is
un-enabled (I think; I have not looked at this code for a bit and it
always confuses me).

Look in pci_probe_dev for example: device is unconditionally enabled,
so we can scan it.

IIRC one case that drove this was multiple VGA cards -- you want to
set up the BARs etc. for all but you really don't know what the OS
will do -- maybe nothing -- but you want them there if it will do
something.

There really is a difference between un-enabled (or disabled) and
hidden; as you pointed out, hidden means no config space, or "will not
show up in lspci".
