Just to close this question, this was discussed at the last device
security call. Indeed the expectation is that Linux will assume that all
ranges besides MSIX/PBA must be present in the report, and that offset
is always aligned. If / when an implementation violates that expectation
they can help write the Linux quirk for that case or otherwise fix their
implementation.
