One of the reasons why hardware vendors want to move away from

Mostly for treacherous computing extensions where subsets of the
config space can only be accessed by signed machines blessed by your
favourite movie company and video card vendor...
I hate "trusted" platform garbage as much as the next guy
(where "trusted" means the actual user can't trust it, just the
seller), but I think there are legitimate uses of extended space as
well, PCIe AER uses it iirc, so don't dismiss it on those grounds. :)
Indeed. It's just a register space. Assuming one register space is
"more evil" than another, simply because it is bigger, is.. well.. silly.
