I lose form data by accidentally using backspace like once a month. Glad to see it go. It's the worst kind of UI modality because it does different things depending on whether you've reached the beginning of the form. I like to mash backspace to clear out a form. Imagine if pressing "CTRL-S" saved if there were edits, but deleted your file if you'd already saved. People who mash "CTRL-S" habitually would be screwed.
It's especially pointless now that everyone has a touchpad or touchscreen and can swipe back and forth.
I didn't say it's available everywhere I said there is another solution (already working in another browser) besides removing a very long lived keyboard shortcut.

I've never seen backspace act differently once I'd deleted everything. If a form field has focus -- even an empty form field -- backspace doesn't make me lose the page.
(On the other hand, I started this morning hating Chrome for getting rid of the functionality I've used since last century, but I'm now coming to accept it.)
To this day, I still regularly copy posts to the clipboard before submitting them, because of all the times I've been burned hitting the wrong button and losing it. (Losing the post, not my sanity! Well, that too, actually.)
