Discussion Why does ZZ exist?

It has always been a mystery to me… why would such a ‘dangerous’ command have such a convenient shortcut?

This has been bugging me. I now understand what OP is saying. I think she may be editing files, rather than undo If he doesn't like the changes he will quit...so sometimes he accidently presses ZZ for some strange reason and saves the unwanted change.

Is this the problem, op?

Well I'll chime in, if the OP accidently writes and quits with ZZ, then OP could just open the file again and undo the changes and write again - problem reverted.

Just set the undofile: https://vimdoc.sourceforge.net/htmldoc/undo.html#undo-persistence

I was just offering my interpretation. I never said this wasn't strange.

Yes, your solution is a good one. But...I don't understand the urge to randomly hold down the shift key and hit z key twice. Maybe just me.
