So this is only because of fundamental-mode?  If so, shouldn't it be
enough to have a possibility to have a predicate function, which can
do anything one likes?

I think we want in general avoid comparison with major-mode, and
prefer derived-mode instead, and if so, IMO we had better did as we
say and not exposed comparison to major mode unless we absolutely
must.
