I think this is very good. I can't tell you the number of times I've lost form data by hitting backspace. For those wondering how, if you do control backspace to erase a word etc igs very easy to miss, especially as you transition between word delete and single character delete. The other common use case for errors is when u think you're in a field editing and you're actually not, bam, you just lost all your form data. I also like the idea that backspace is for text editing and not for a second feature such as navigation. For enter yes but not backspace
