OK, doing so.

I'd just go for RESOLVED INVALID. We don't want to remove the code that
implements a supported feature.

Changing from WAITING to SUSPENDED, that seems more accurate

#pragma once

Can you explain why you think it can be completely ignored?  It can be used
without macro guards.

Ah, you are correct--old code may have that only.  How about a warning instead
about using the recommended construct (the header guard) instead of the pragma
once?

At one point we deprecated it and then undeprecated it.  See PR 11569.

Oops, I missed that PR.  I still think that an optional warning should be
there--something like -Wpragma-once with a message about the better practice.
(Sorry I missed finding the original bug--I only looked at open bugs--I now
know better.)
