It used to be used with preallocated packet buffers with
the old encode API, but said API is no more and therefore
there is no reason for this to be public any more.
So deprecate it and use an internal replacement
for the encoders using it as an upper bound for the
size of their headers.

Encoders (usually) have no business modifying frame->data
(which need not be writable), so they should use the appropriate
pointers.

Also allocate the AVFrame during init and use av_frame_replace()
to replace it later.

A private class for an encoder without options is useless.
