Exactly!  As Ximin says, the thread you included was from june 2015.
The message you show was not really a discouragement but a suggestion,
so it must be taken as any other suggestion, and I believe that the
message was not from a gcc maintainer.

The thread that Ximin included is the most recent discussion, see the
beginning here:
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01890.html.
Basically I took the original patch and modified following the
suggestions from the gcc contributors in the original thread plus review
by the Debian gcc maintainer Matthias Klose <doko at debian dot org>
(you can follow the thread to learn more).  Eventually the gcc people
seemed to have no further complain about the patch; I even signed the
copyright assignment.  So the last message was that they are now at the
stage of fixing bugs in GCC 5, and they asked me to send the patch again
when the new feature stage for GCC 6 starts, which should be around
April 2016 :)
