Yes, this is primarily the usecase here initially. As some point a
renderer would rather duplicate previous frame than rely on
reconstruction. This could be done within EC itself but letting the
decoder make this choice rather than exporting the information to a
renderer and doing it there seems incorrect to me.
It is the intention to expand the metadata to provide information about
specific regions in the frame in the future but mainly just providing
the framework for providing this sort of information in the first place
at the moment.
