I used to need one setup at work and a different one at home (because of
how my email was configured), and sometimes had to switch back and forth
as I carried my notebook around.

I know it's *possible*. The question is whether it could be made easier.

That would be helpful, but it would put yet *another* requirement on the
submitter (to send patch emails *and* push the branch to some accessible
repository). We regulars could script this pretty easily, but people who
only contribute occasionally or who are trying to get started will be
even more overwhelmed.

Yes, but it is even more unnecessary manual bookkeeping.

Yes, good idea.

One day per patch might be exaggerated, but I agree that long series
should be iterated more slowly than short ones.

One has to run an additional command and add some information to the
cover letter, every time a patch series is submitted. If it's scripted
then it's relatively painless. But for a newcomer these will be manual
steps that are easy to forget or to do incorrectly, making it more
likely that the newcomer's first contribution to Git will end in mild
embarrassment rather than success.
