2. Redundant data path

Client maintains two data paths to the remote party, one direct p2p and another with lower bandwidth through a different network path like a TURN server. If p2p connection fails or experiences packet loss, media is recovered using packets received over the alternative media path.

You're talking about two different things:

- graceful switching
- multipath

One is harder than the other.  Which one do you want more?  Or do you just want both?

[BA] Graceful switching can be provided via TURN mobility [RFC8016]. AFAIK this does not require any API changes (it is supported already in ORTC lib and its WebRTC 1.0 shim).
