That would be addressing diagnosability, or more specifically the accessibility of this diagnosability to system and network admins.

I was pointed to RFC 4787 already.
This continues to be great background material, but I’m not sure that is a very realistic document to point network admins to, today.
A more restricted set of “this is what you really minimally need to do” might be a useful companion.
Also, exposing any diagnostic information that already is there and that of course every WebRTCer knows but unfortunately nobody else.

Definitely that (e.g., getting rid of DTLS 1.0), but of course the developers are approaching headless chicken mode already with all the recent attention.  So I was thinking more in the direction what we, and in particular the instigators of WebRTC, could do to make life more productive for both the developers and the admins.
