This sounds like these two pseudo-classes would do exactly the opposite.
So why not use :not() for this case?
That question was asked and answered here:

Apparently an invalid dropzone is one that accepts drops, but not of this
type, so it's not exactly the same as :not(:valid-drop). I'm unsure if
it's necessary to add at this point, but can add it and mark at-risk for
the time being.
