It's not deprecated. It has some issues, but it is supposed to become
the recommended way to do network transparent audio. So, it's
everything but deprecated.

As mentioned many times on this ML already, right now there is no
module for linking a sink and source directly. This is is not as
trivial to write as one might think because adaptive resampling is
required to cope with deviating crystals of the sink and the source in
question. But it's doable, And on my todo list.
