I think what was confusing is that the name "Hangouts" use to mean only
"group video chat", but ever since the product launch at Google IO this
year, it now also means "group text chat".  Much of the "recent noise", as
you call it, was actually about the text chat, not the video chat.  The
video chat portion didn't change much;  it still uses Jingle for signalling.

However, after having written my original "we still use Jingle" email, I
realized that there is an important point that might effect you:  the
Hangouts group video chat doesn't support third-party clients.  So from
your perspective, I admit that the fact that Hangout video chat uses Jingle
for signalling is a bit of an implementation detail, as Emil called it.
