> elm-review doesn’t have severity levels, meaning that all enabled rules are enforced. Yes, no warnings

Imo, this misses an important use case for warnings: reporting issues that I don't want in committed code, but that are fine while developing. For example, dead code — I don't want to commit a function that's never called, but I do want to be able to compile/run my code and run any tools over it when I've written a new function but not yet called it.
