I'd assume that there is a class of users who never ever use any keyboard short deliberately (because they are not aware or dont care about their existence). Any keyboard shortcut they trigger is pretty much by accident. I have not data how common that is, but I know such users.

That seems to just be majority of users based on that stats listed above, and that backspace is the only one that is trivial to hit when trying to do something else.
