I think you just widened the meaning of "safe". :-).

In general I might agree with you. However, .EX/.EE and .DS/.DE
have a couple of interesting properties:
1. They are, by far, the most commonly invoked man macros that don't
exist. :-) That is, significant numbers of man-page writers think they're
there already.
2. This fact has gone unnoticed mainly because the errors you get when they
no-op aren't too severe.
So there's an argument that we'd just be supporting existing practice if
we put them in.
I don't think your citation of -mdoc is really on point. IMO, the reason
it hasn't gained acceptance is that, while -mdoc markup is cleverly designed,
it is also quite complex -- more heavyweight than most man-page writers
want to deal with.
