It is. Nico is also probably working on it.

My big concern with pack v4 right now is the on-disk format of
commits/trees is different from the current wire protocol. If a pack
v2 only client connected to a server using pack v4, the server would
have to spend a lot of time to inflate/deflate about 60% of the
objects in the repository (commits and trees). That is a lot of CPU
time. So even if a SoC-er finished the work, it probably wouldn't be
merged because of this penalty.
