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.
