Hi Harald, 

Is that a google position or just an assumption?
I don't think anyone has an issue with WebRTC-Compatible endpoint. 
Assuming browsers have to implement both and that this question is out of the way.
The remaining point is the 'non-browser', which is already differentiated by the note, and it is acknowledged that (over time?) they may only have one codec to implement. 
I don't see why revisiting the  non-browser category is a problem.

Gaëlle

It is not clear that the questions are independent.

In fact, it is pretty clear to me that some participants who were willing to go with this package deal were quite unwilling to commit to all the pieces of the package if they were presented one at a time, and they had to answer the question not knowing how all the other pieces came out.

I think this is a textbook case of a "package deal".
