Not at all. It is the correct default situation, of course, that a 4x4 is not required. However a good survey of roads that are remote should consider including additional detail on the road surface. Absence of this tag on a road (especially when aerially mapped) is no guarantee that a 4x4 is not required. 4x4_only=no is a useful observation to annotate (amongst other useful tags and annotations). I'd hate to think that accurate survey data that a 4x4 is not required on a remote road is removed because someone thinks that is the default, so the tag is useless. Or worse still, does a selection for all such tags in JOSM and deletes them all on the same basis.
