Yes, the change starts from HSW. I'll update the patch.
what's the "rant" I need to insert? I was not in the list a year ago:),
having some trouble find the email as reference.
Any archives I can look into?

Iirc 4kx4k is allowed on hsw already, albeit with the lower 2k lines being
uncompressed. Please double-check bspec and update the patch.
Also: Please insert rant here that I've written a mail a year ago about
the piles of little issues in our fbc feature checking.
