It is very hazy memory of mine that starting with F10h, we had an MCFG
table always present but I don't remember anymore. Maybe I'm even
remembering it wrong.

In any case, as Andreas and I pointed out, this is AMD's decision so if
they're fine with F16h, then it is definitely not my place to disagree.
