If the standard is not correct or complete, the standard can be
fixed/extended.. REVmc is in the sponsor ballot and comments can be
filed against the latest draft to request changes. I can do that in the
next round if you can identify the proposed changes that would be needed
to make this functionality work properly.

I'm fine with wpa_supplicant/hostapd not following the current standard
if there is reason to believe the standard is not correct. As such, I
don't think we have to remove the current behavior. Once TGmc has
reviewed the comments, we may need to change the implementation to match
the outcome from that review, though (if nothing else, to move the IE
into the correct place which is unlikely to be the current location).
