[issue40633] json.dumps() should encode float number NaN to null

[Raymond Hettinger]

One other issue just came to mind.  While we could convert NaN to null during encoding, there isn't a reasonable way to reverse the process (a null could either be a NaN or a legitimate None).  That would limit the utility of a new optional conversion.
