For the record, Christopher Degawa also posted something similar
(https://patchwork.ffmpeg.org/project/ffmpeg/patch/20210310224859.1726693-1-ccom@randomderp.com/),
and I finally recently had gotten to noting on IRC that the rate
control options should be brought more in line with, say, libx264. Set
AVOption-specific defaults (f.ex., libx264 sets CRF to its default
value by default), and then if any of the other rate control modes is
nonzero the appropriate rate control would get utilized in the
wrapper.
