Promises will help here, but good APIs are not in contraposition of
languages failures. Merge this calls maybe it's a little bit of sugar
syntaxis, but it's not a bad thing at all... But definitelly, I don't
agree with the sentence about "WebRTC is designed to build wrapping
libraries". Low level is ok, but should be easy to use "as is", if you
are forced to use a library you are learning to use that library, not
the APIs that offer the browser.
