Warnings are good, but it's a pity there's no good warning suppression method which is compact (and does not require to disable the warning on the entire file).

People generally "fix" warnings by writing equally useless statements like "x = x" (common for -Wunused). I've seen codebases which aim for zero warnings, but with -Wextra/-Weverything it's just silly. Warnings are supposed to be just that: warnings.

I'd rather want a clean way to suppress the warning and mark it as such instead, so that's hidden by default when the programmer takes note of it.

We have push/pop pragmas, but they are even worse readability-wise. I'd rather have a neighboring comment with dedicated syntax instead.
