Personally, I'd prefer that other units be consistent with lengths in this regard, and allow zero to mean zero of any any and units, rather that make less experienced authors wonder what the special rule is for some properties to allow unit-less zeros and not others (after spending time isolating the problem). Can't we just create syntaxes in which zero is always unambiguous?
