Thank you, will update this. FYI: The entry was mostly copied from the
X86 PLATFORM DRIVERS entry, so it should probably be updated there, too.

I agree with (2) and (3), but I'm not so sure about (1). For Chrome, the
entry is CHROME HARDWARE PLATFORM SUPPORT, so should I change it to
MICROSOFT SURFACE HARDWARE PLATFORM SUPPORT?
