I agree with this. 'Valid is (almost) useless combined with UC, but that
is true whether or not UC is erroneous -- in most cases (other than
[very] sparse enums and float values) it is trivial to check before
applying UC. So it isn't needed in those cases. That can't be done in
the other cases - C or a file could contain anything.

Nothing that I see. The ARG discussion was narrowly focused around
'Valid and UC -- perhaps not everyone realized that.
