It’s a bit odd, but since these are diagnostics, why not use the existing -W

Good point. I will prepare the above patches such that they reuse the existing
infrastructure. If we really see a need for further adjustments, we can do this
incrementally.
Yes, this is sounding good. Keep in mind that it may be preferable not to
permit upgrading remarks to errors (another potential use case of this being
informational diagnostics about system headers that aren't user-actionable).
Warnings already default to being suppressed in system headers, remarks should
default to the same behavior.
This is for -Wsystem-headers or similar as a utility to identify
workarounds that have been activated to support quirks in system headers.
