Well, no. The objections to a fork in this thread are based on
(very reasonable) concerns about duplicated maintenance effort,
lack of one source of truth, and so on. This would not be that.
However, you have a very good point that if any significant number
of vendors start including backzone to restore some approximation
of the way things stood before, then there is going to be the same
mess from end users' standpoint as a true fork would produce. There
will be more than one "canonical" version of tzdb, and that's going
to be barely distinguishable from a true fork in terms of confusion
on the ground.
