I think we also care in the sense that what we put in the reference
platform is an implicit recommendation. So if we (collectively) think
that good Arm server platforms are likely to or should use XHCI,
we should definitely consider going with that, rather than going with
what happens to be being used on currently shipping hardware.
(We should also consider whether we want to implicitly recommend
that the USB controller should be memory-mapped rather than
hanging off a PCI controller.)
