Brandon Williams commented on CASSANDRA-5127:
---------------------------------------------
v2 consolidates everything into getTokensFor.
bq. I'm not of fan of have a usesVnodes method because if I'm not mistaken any
upgraded would have this method return true even if only one token is used
Not quite, to have the TOKENS app state you must be on vnodes. If there's only
one token it's handled the old, ugly way by splitting the STATUS state.
