Now that's a disappointment indeed. But then you can still see the persons who regristed later and the ones who aren't regristed anymore due the database wipe are considered older then? That way you can still find out pretty quick. The leftovers are older then November 2009
A more practical question: Should my suggestion make it in a way (like (year) 'veteran' coat or veteran tag or a JJANG), What would be the estimated time to have it realized in the actual game? Would it be with the V8 update or something (no clue when that is tho)?
