One of my friends does this all the time and doesn’t realize for a good 5 minutes, but I’ve only had it happen once to me.
I guess the issue with changing it to something less used is… wouldn’t that just make it happen more often to someone on a different control scheme where that button just happens to be more common for them? What’s used often for one person is just going to be less often for another person’s layout, and vice versa.
