No, i don't think, Andrew is too hard here.
As said before: in some special cases enum makes sense, like you said:

But the problem are really not this special cases, the real problem are
all the people who don't understand about enum and just try to use it
because "it seems to fit best" - unless they run into problems.
So we have a good tool in your hands, we just have to tell/teach the
people, how to use it and especially when not to use it.
Kind regards
