Good call on reformulation as `not X and not Y`, I'll take care of that. I'll
also try to reword the "vacuously conform" to be more clear. The intent is:
because the changes in the paper only apply to Annex F, and Annex F support is
optional, and we don't claim to conform to Annex F on any target (and we will
never claim to conform to Annex F for that particular target), we conform to
the paper by doing nothing.
