Eric Evans commented on CASSANDRA-1031:
---------------------------------------

{quote}
how would you make a client supporting both 0.6 (String keys) and 0.7 (byte[] 
keys) otherwise? call methods that only exist in one or the other? i suppose 
that's workable but it's a little ugly.

These are differences in the API. Do you have in mind some way in which the 
release version better indicates this condition than the API version?

{quote}
what are the downsides to exposing it over thrift?
{quote}

That it encourages people to use it for gauging API compatibility instead of 
using the more capable API version (more capable because it does not move in 
lock-step with releases, and because it also encodes the type of change).
