The first reason is consistency, besides bisect, all other in-progress
commands have both --abort and --quit.

The second is because it's an escape hatch suggestion in git-switch.
And this goes back to the first reason because git-checkout will just
let you switch and do stuff. If you forget about the merge, at some
point continue the merge won't even make sense.

No opinon here.

I do have three small patches to refine git-switch. But I think we can
do it on top. Probably best that way anyway to keep the justification
for the changes in commit message.

git-restore works quite nicely for me, by my opinion in this area does
not count. Besides Emily's usability issue with shell wildcard
expansion, intent-to-add support is still not there. And Phillip might
want to change --discard-changes behavior. That's all that's left.
