Stuff that just does obvious code removal may _look_ big, but I
actually think it's conceptually a smaller patch than the subtle one
that just made the code impossible to enable.

Marking something broken implies that maybe we'll be able to fix it.

This seems to be more of a "let's just get rid of it".
