Very simple: nobody has bothered to port/maintain it, there have been
requests to make the sink functional again but that's usually not enough
to get something going.
Technically we allow sinks in pull mode (as we always have done since
0.6, or so) and the optimal way to implement an audiosink is when the
lowlevel API supports pull mode. It's also a lot of additional work to
make sure that all decoders/demuxers support pull mode so that you can
build a pipeline that works entirely pull based.
