Nothing good could come out of putting negative values into any of those functions.
And they are used a lot in image loaders which often can be tricked into passing large enough values to make those functions be called with negative numbers.

Having too many warnings makes it harder to see real warnings.
I know the idea to keep those around was to have them as reminder to work on those.
But going over the formats here - it just doesn't make sense in most cases.
And for the rest (like we could add converts from R8 or so) no-one is going to work on it until someone concretely needs it anyway.
