That's a nifty option! In (neo)vim, I like to use the ZZ keybinding to quickly save if modified and then quit. If I want to abort the commit, I'll type ZQ to discard changes and quit.
Ya, it's somewhat surprising that ZZ isn't the binding that is burned into people's minds instead of :wq<cr>. I've even met regular vim users who don't know ZZ which, to be a bit hyperbolic, is mindboggling.
EDIT: And of course there is vim -y to make vim behave more like a "normal" editor than even nano :D (ie, you get ctrl-s and ctrl-q).
For me, it's because when I learned BSD 4.2 vi in the mid-80s the emphasis was on learning the decomposed commands then building up. If you learned w and q , wq is obvious and non-magical.
I've been using vi variants for decades and didn't know ZZ or ZQ. This solves a major pain point for me (mis-typing :q, trying again, now I'm off in the weeds).
ZZ is particularly nice since it sorta "does the right thing" in that if you have an unwritten empty buffer, it will silently discard it and quit. I guess I haven't really run into this as I was taught ZZ from the beginning but I imagine hitting :wq<cr> on such a buffer is pretty annoying.
If you are in `git commit --amend` or am/rebase/cherry-pick, the message did not start empty, and using ZQ will proceed with committing. :cq is a good idea.
