You are talking about the implementation of the refcounted structure. I
was talking about when we use the refcounted structure. Your version
makes every single use more complex, because of the indirection.
This is something to know about code I write with new APIs: I always
make efforts to make the API as simple to use as possible, even if it
means making the implementation more complex. Because the implementation
is done only once, but using the API will happen many times.
And this is exactly what happens with your proposal: a refcounted
structure defined with it would be more annoying to use because of the
indirection, and I will not have it.
If you have a proposal that makes using the refcounted structure as
simple and clean as:
av_foobar_ref(AVFoobar *f);
av_foobar_unrefp(AVFoobar **f);
then I will listen. But if you have type pruning or indirection, then my
proposal is superior.
