Why would the AP explicitly need to check for HT/VHT capabilities on the
6 GHz band? Wouldn't it be sufficient and less likely to cause interop
issues by simply ignoring those unexpected HT/VHT IEs? Or is there some
clear requirement in the standard for the AP to do this type of
validation step?

IIUC HT/VHT operations are prohibited on 6 GHz band. no? Hence rejecting buggy
stations that announce HT/VHT capabilities on 6 GHz band. Do you prefer
to allow such stations?

The HE capability check looks fine, but please split to a separate patch
without these HT/VHT checks.

Sure.
