  I realized this might be mis-interpreted.  The "well past time" was 
really meant to signal that I think we probably should have made this 
change long ago and that waiting even longer just doesn't make sense to me.

I'm fully in favor and have no objections to making it now.  I wouldn't 
be terribly surprised if it's less intrusive to make now rather than 
after gcc-12 is released.  Making it now affects trunk->gcc11 and 
earlier backports which should be smaller than trunk->gcc-12 backports 
we'd be making in the summer/fall if we were to defer until after gcc-12.
