(Wrong mailing list?)
No, and I don't know if anybody is actively working on it.
I suspect there are enough samples.

Otoh, what do you mean with supported?
It is supposed to work fine with MPlayer over HDMI to a 
DTS-HD Master receiver, and of course it has to be "seen" first.
Could you elaborate?

I am not sure if I understand the question.
You can test the following:
$ ffmpeg -request_channels 2 -i input out.wav
$ ffmpeg -i input -ac 2 out2.wav

The first does decoder-downmix, the second downmixes 
through the libswresample library.
MPlayer by default requests decoder-downmix iirc.
