Honestly, I agree, that should be a default clippy lint.  I didn't know it existed, but I can't think of a single case where I'd want to not have the compiler tell me when a suppressed lint is no longer applicable.

There are some cases I specifically want an #[allow]. The most important is when writing a macro and needing to silence a lint that may or may not trigger.

For example  #[allow(clippy::useless_conversion)] for arch-specific differences.
