Not definitive. He appears to be busy with other stuff. Branko is
implementing the vcdelta algorithm. Nothing in Subversion really
requires that vcdiff be the transmission format for text delta
windows; if Branko thinks some other format is better, maybe we'll go
with that... (i.e., any reasonable format is probably good enough, it
doesn't have to call itself "vcdiff" -- but vcdiff is one format that
looks good).
I don't think an Internet Draft's expiring makes it any more dead (or
alive) than it was before. If people use it, then it's a standard; if
they don't, then it's not.

The work required to use xdelta seems equivalent or greater to that of
just implementing vcdelta (at least when I was examining the issue in
detail a while back), and Branko has already started on vcdelta stuff,
so I don't see a reason to change...
Unless you have, or will soon have, a working standalone xdelta
library -- that would change everything! :-)
