Woo! Bike sheds. So.
Yay more names!
Veteran researchers can rid themselves of the pain of old names, but new researchers shouldn't have to deal with legacy naming.
I don't see us getting rid of legacy naming right now. I don't see how adding a new name helps anyone -- veteran or newbie.
However, if we were to develop a mapping of canonical names and pursue that from here forward, we might be able to move beyond the old names for the most important data sources in a few of years. However, I'm skeptical that we'll ever be able to change any production DB field names.
