Hi

My experience with implementing this spec (in WebKit) is that these
detailed steps are rather helpful and actually defines a lot of the
behavior. E.g.:

* 2.1.1.1. defines how the options string should be parsed.
* 4. defines how the serverConfiguration should be parsed as well as how
the initial offer should be constructed. Details in this section also
affect the behavior defined in the addStream, removeStream and
processSignalingMessage sections.

Just removing these sections would defiantly make the spec harder to
implement in my opinion.
