--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Noone disputes it's not conforming. The point is the support is incomplete.
It's known to be incomplete. It's documented as incomplete.  Reporting a bug to
say it's incomplete doesn't serve any useful purpose, it will be complete when
it's completed.
