I've had a look at your references and would counter with yes,
necessary. The solutions you are talking about are fully fledged VC
solutions; they need channels for all sorts of stuff. They need to set
up separate connections to carry data of various sorts, so that those
connections can be managed independently of each other, so that they can
have appropriate shaping applied independently of each other, and so
that each can rely on the network for the services it requires (like
reliability in the case of TCP). Separate connections also allow the
streams to be handled by separate devices if necessary.

Of course you could develop your own complicated multiplexing inside a
single stream (and some codecs do that, partly) but you lose all of the
above flexibility and power.

Personal VC, like Skype or some open standard, is far less demanding.

Indeed it can be. What luck that we will shortly be rid of the NAT that
has made it necessary.

The discussion shows only that NAT is a pain.
