Yup, I had seen this. And I think this is a good idea for such a
critical piece of code.

Why so? I think on the contrary we should keep the default, and only if
we find issues then we can investigate as to whether this is a real
error or not, and report that upstream.

Granted, we usually remove -Werror from packages when they fail to build
(and I am not a big fan of it, warnings should not be treated lightly),
but only in that case. If the package builds fine with -Werror, we
usually keep it.
