I think also this proposal do require an Internet draft which discusses
the requirements put on the API. What of the underlying protocols that
are this WG task needs to be exposed in different forms?

My understanding of your idea is that you have both capabilities and
knobs that can be set. I also believe it requires some state
transitioning events. For example to kick of ICE negotiation between the
peers when the right things has been set.

Thus, I personally do see a need for draft from you that explains the
details of how things are expected to work. I don't see you needing to
define how the API should really look, but what the requirements on that
API are based on your solutions. But without that your proposal is still
not clear and open for a lot of interpretation.

Cheers
