I suggested this last year already:
From what i remember, this suggestion was not favoured
IIRC, after this we then eliminated all parts that can be and used
the linker with registering just the needed components to reduce the
size to within the constraints

ffmpeg-devel really is the wrong place to discuss this.
The best bet is probably just to implement it (make sure it works, existing
testcases still reproduce issues, stack traces still are useable, ...)
and send a pull request to ossfuzz (with a CC to me or ffmpeg-devel)
Iam not able to say yes or no to this as i simply do not know why some
of the preferrances in the design exist.

If you fake or manipulate statistics in a paper in physics you will never
get a job again.
If you fake or manipulate statistics in a paper in medicin you will get
a job for life at the pharma industry.
