Argh!  Feature creep!

The reason that rm should have it but chmod should not is that it is
to work around the POSIX nanny rule around '.' and '..'.  Chmod does
not have such a nanny rule and therefore does not need that option.

This is actually the best argument against it.  It is a slippery
slope.  Let's not implement 'find' all over again.
