I didn't mean to list those alternatives as only possible
alternatives.

The point is people have their own preference to choose a scheduler
that suites their need.

Someone could use their own supervisor system with things like:

	#/bin/sh

	sleep 3600 # 1 hour
	exec git cmd

When "git cmd" exit, the supervisor will start the job again (because
it's down and it needs to be run).

That will be too many possible solutions out there,
I'm still not convinced on adding a scheduler to Git.

Yeah, I knew it. t3701.{44,46} is also fixed with the builtin.
But, it will be some version into the future to be enabled by default.

The point is there're people that don't want to see a new hard
dependencies for Git.
