The point of the announcement is not to repeat all the information
that is already provided elsewhere (specifically on the page the
announcement links to), and since the experimental status didn't
change there's nothing to announce w.r.t that status.

I think you're just being picky - does it really matter?

No. That has never been necessary.

Exactly. It would be premature to announce them while I'm still fixing
the fall-out.

I still don't understand what a C++14 announcement has to do with the
status of C++11.

The entire thread seems to boil down to "I'm not happy with an
announcement of X, why doesn't it also make an announcement of Y?" so
I'm going to stop wasting my time in this thread.
