        Compilers add new warnings all the time. If somebody tries to build your code with a newer compiler than the developer used (which is likely, if they're building anything other than very recently written code), they may hit a new warning and then get compilation failures.

        As long as CI builds have `-Wall -Werror`, I don’t much care what people do locally on their machines. But *something* needs that level of rigor or else you release this: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00092491en_us …

        I don't think errors from warnings in dependencies actually error the build.

        -Weverything -Werror -Wno-...someWarnings has served us very well so far, but we do not make public builds. If you can enforce this for CI builds and be a lot more per missing on public builds great... but then you need to have a well diverse and updated CI agents setup.

        Some of those warnings only your customers get may be important.
