True, that there are flags to turn such warnings off. Each compiler has its own variants for this. But well, why we should rely on such things. As you already mentioned, are our headers system ones, and therefore as silent as possible. Nothing is worse in experience to users, if they suddenly see warnings, they don't want to see. And that all because they enabled some warning flags for "their" code.
