For 160-350k a lower complexity codec probably made sense.

I think the same that Garf about it, basically they want to sell a license for it.
I wonder why they didn't just use Opus instead of creating a new codec?

If you look at the specification, it's basically Opus with a few marginal gadgets thrown in. I'm going to make a not-very-wild guess that you'll need a license for the gadgets, from the people who wrote the standard.

Will this codec at least introduce good quality bidirectional audio into the official Bluetooth LE stack? (eg. gaming headsets with simultaneous input/output audio paths)
There's a hackish solution called FastStream for classic Bluetooth, but the bitrate budget is very low for the used SBC codec (212kbps down / 72kbps up), so it's probably acceptable for game audio but nothing else.
WavPack -b4x4hc
Opus --cvbr --bitrate 256 --framesize 5
