No, and the previous spec spoke explicitly to solving this by using the

More importantly than that, there are a large number of geographic
coordinate systems that are Lat/Lon that *aren't* EPSG:4326:
http://spatialreference.org/ref/epsg/?page=29 has a long list. I'm
narrowminded, but if we actually want to *solve* the problem, making
EPSG:4326 a special case doesn't do it. Maybe we don't care about
solving the problem, or maybe we feel that calling it EPSG:4326 and x,y
isn't a problem: either way, it's not actually solving the general case
-- which we'll need to do if we care.
