One problem is the updates in toolchains that come up with new warnings, a lot of which are nuisances. Developers get tired of the make-work which that generates, either to fix the warnings or else identify where they are coming from and put in options to stop them.

The real problem are warnings that are super-useful (find a bug) about one out of twenty times (or less). The other nineteen times, they are false positives, such that refactoring the program to eliminate them is a fool's errand.

You don't want to turn off these warnings, and you don't want to fix all instances. So then you need per-file warning disabling, or start using compiler-specific #pragma-s:

   #pragma GCC diagnostic warning "-Wno-whatever"
