--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
btw in practice the fact this is SUSPENDED today is absolutely no different to
the status yesterday. It didn't work in GCC yesterday and it doesn't work
today. The only change is I've publicly stated my intention to discuss this
with the committee before doing anything here.

I could revert the status, and still do nothing here, but that serves no
purpose.
