Bandwidth is one thing but the other thing is that git network
operations require that the whole operation succeeds in one go.

If your connectivity is bad to the point that the TCP connection breaks
you have downloaded a bunch of data that is AFAIK just thrown away when
you retry.

It is difficult to know if that data would be useful in the future, and
you cannot meaningfully 'resume' because the remote state might have
changed in the meantine as well.

Further, this whole fetch operation is using a heuristic to fetch some
data in the hope that it will be enough to reconstruct the history that
is requested, and this has been wrong in some cases, too. Not very
precise and reproducible hence hard to 'resume' as well.

Let's say that the git networking has been developed at and tuned for
the 'first world' Internet, and may be problematic to use in net-wise
backwater areas. And it would require non-trivial effort to change.

Thanks

Michal
