Maybe as an opt-in (mode or blanket approval), having to continue on every compiler error which has a fixer would be rather frustrating. Clippy supports fixes, but will only apply them if `--fix` is supplied. It does not ask for individual case, the assumptions likely being that if you're running this opt-in you can probably do so with a clean working copy and revert whichever fixes you didn't want or are incorrect. An other issue is if you're providing fixers for suggestions, the fixer has to be extremely reliable, not a 90% thing, because replacing broken code by possibly subtler broken code is not great.
