I agree with you in that's the way to go, but there's another issue:
trickle ICE. Without the hability to disable it, the offer description on
createOffer/createAnswer is fairly useless by don't having candidates. And
yes, needing to wait for externally dispatched candidate events is
counter-intuitive, after all this time dealing with WebRTC I still forget
them when creating new code code from scratch. Trickle ICE should be an
advanced functionality behind a flag (the same as your proposed sdpMangling
flag) instead of a by default feature if we really want WebRTC to be easy
to use by newcomers. I think this will greatly help to increase WebRTC
adoption that releasing a 1.0 spec soon, and it's a thing that will not
delay it beyond than one release more.
