The _only_ reason the side data is opqaue is because side data can't
contain pointers, which again is because side data must be a flat byte
array for legacy reasons. (Yes, we should change this, but probably
can't now.)

So I think all what you've been writing can be reduced to: should this
really be side data, or would it be better to just make it a new
AVStream field.
