I'm also just a simple engineer, unclear on what has to go in a charter and
what doesn't.   But it sounds to me like we're all trying to decide on and
agree upon what "1.1" and "compatibility" mean right now, even though we
could just as easily decide that later.  Could we simply change the charter
text to the this?

"As the name implies, WebRTC 1.0: Real-time Communication Between Browsers
is to be considered as a first version of APIs for real-time communication.
The working group will, once WebRTC 1.0: Real-time Communication Between
Browsers reaches Candidate Recommendation, consider proposals for the next
version of APIs."

Then we could save all this discussion for what "next version" means after
we have the charter to make one, and the process of chartering wouldn't be
