New description:

 When you clean a `RangeField` and pass it in `('', '')`, or `(None,
 None)`, it falls through to the `MultiValueField` handling, which, when
 all values are empty,
 
[https://github.com/django/django/blob/a6b5321ce997b899e540bb427cca98cb2b93a106/django/forms/fields.py#L992
 treats the cleaned value as empty].

 Thus, `FloatRangeField().clean([None, None])` returns `None`, when it
 really should return `FloatRange(None, None)`.

 There is a very large difference between these.

Comment:

 I'm not sure -- could you elaborate on the use case? How can you submit a
 `[None, None]` value in an HTML form (or are you also advocating
 transforming `['', '']` to `Range(None, None)`)?
