The 0.20 append solution has never been seen as a fork. It's a stop-gap
fixup of the 0.20 append feature, but we don't intend to forward-port that
append implementation into trunk. From an API perspective it's very close to
the 0.22 version, and I think everyone fully intends to abandon the
0.20-append work once 0.22 append has been heavily tested for HBase
workloads.

+1. Interestingly, the work on 0.20-append uncovered a number of bugs that
also will apply to 0.22's implementation. So it wasn't all a wasted effort
;-)
