It wasn't?
There were simply no objections to moving to C11.
The C17 plan came about later because it has important bugfixes.
It doesn't really matter as compilers backported the new behaviour to C11
(or rather, they consistently had the same behaviour, but now it became a standard).

I think there is consensus. No need to be careful or conservative,
this is a build-time bump. We've had those before, such as cuttting
off support for MSVC prior to 2015, and non-C99 compilers
(via the horrible C99-to-89 script).

Users who have real issues can always leave their opinion here,
and if not, we maintain FFmpeg 6 still.
