Hi Phillip,

Sorry for the late reply.

I think that since this option clearly applies only for a
restore-type action and there are checks in place to ensure that
the user is not attempting to use it for a switch-type action, it
doesn't introduce much more complexity than the `git restore --worktree`
option does.

I don't think it'll hurt to provide more than one way of doing it. As a
pretty long-time user of git, I've been having trouble picking up the
switch/restore commands in favour of good ol' checkout due to muscle
memory. I agree that I should try and switch over to these new commands
but old habits die hard and I think it would be much easier to just
provide this option to checkout.

Thanks,

Denton
