That's fine that still doesn't necessitate pulling this into 0.96.
The rpc has the ability to specify what Codecs are usable.  That
should allow the creation of new block encoders and new apis used in
HFileV3 and allow the older versions to co-exist perfectly well.  That
should mean that it's possible to make this change in a later version
without holding up 0.96.
