I'm not sure exactly what the scope of this issue might be, but I think it's worth asking at least. It appears to me that if I do something like querying Vizier for catalogs of objects, while I can return their standardized _RAJ2000/DEJ200 columns, there's no straightforward way to get back a SkyCoord for the catalog without manually creating one myself. Has there been any discussion about whether this is desirable? I can think of some clear ways to do it in e.g. Vizier or SDSS, at least now that astropy tables support returning tables with columns that are objects... But I'm not sure how general this should be. Is there someplace that could be plugged into that would allow all astroquery tables with appropriate column names or something to get an added skycoord column? For that matter, is this desirable?
