Can't argue with anything in that list. I think it would also be useful to survey people who looked into using Rust but decided against using it, as responses from people who suffered through the warts is analogous to looking at the damage to bombers that made it back to base. Still relevant, but not the whole picture. I'd expect to see mobile/cross-compilation (which I know is getting better) to rank pretty high among people who didn't stick with it, but maybe I'm projecting.
