Personally I think it is reasonable to expect manufacturer-provided
config space to always be in the same place, regardless what kind
of executable rom is there. Then again most vendors seem to think
it's unresonable, and even if it wasn't we'll have to make sure our
drivers work with whatever it out there - so this discussion is
rather moot.
