By the way: do we have any mechanism for explicitly suppressing
individual warnings (some kind of annotation), when the maintainer is
sure that some particular case is a false-positive ?
(I'm thinking of something similar to certain #praga directives for
explicitly ignoring invididual warnings in specific lines of code)

I believe such a feature, so we don't get spammed with the same false
positives again and again.
