I guess we will need to add another list type/exception if we decide to
continue to support the + syntax for groups in valid users (which does
not exist in the source4 code at the moment anyway). 

That said, I think this parameter is terribly overloaded, and given that
all the examples I've ever seen are for @group, and that NIS for which
the difference mattered is effectively dead, I think we should simply
decline to support + and & for 4.0, if we can't come up with a better
replacement for the whole 'valid users' thing.
