For example, dequeuing output buffers in decoder order.

Indeed dequeuing in decoding order is obviously possible with stateless
interfaces. But it is often possible with stateful interfaces too AFAIK,
just not with V4L2. For example, we have this option on some of our
targets because the codecs are exposed using OMX with some vendor
extensions. This is a stateful interface.
