Since old ones had a buggy git bundle command.
In particular, git 2.30.2 has a git bundle that supports --stdin, but does
not read from it, and so fails to create a bundle.
While not using --stdin would perhaps work, it limits the number of revs
that get included in the bundle to the command line length limit.
But the real kicker is that at the same time --stdin got fixed, a bug also
got fixed that made git bundle skip including refs when they had the same
sha as other refs it included. Which would lead to data loss. So best to
avoid that buggy thing.
Full pushing will probably work, but is untested.
Incremental pushing is not implemented yet.
While a fairly straightforward port of the shell prototype, the details
of exactly how to get the objects to the remote were tricky. And the
prototype did not consider how to deal with partial failures and
interruptions.
I've taken considerable care to make sure it always leaves things in a
consistent state when interrupted or when it loses access to a remote in
the middle of a push.
