Thanks for the report.
I think basically what you are talking about is the same as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766397
which was forwarded to emacs-devel, which is a great way to ensure
things get lost, so it's good to have an actual bug report for it now.
The discussion is here, but AFAICS nothing actually happened:
