As an implementor of an application on a host acting as a, say, a
SIP phone I do not not understand how these mechanisms are going 
to help me at all.

First, how do I know if the underlying OS version supports NSIS,
for instance? And even if I do know that, that says *nothing* about
the support in the one place that truly needs it, namely in the
routers in between. So all this appears to do is negotiation of
mechanisms between two parties who have no clue about what mechanisms
are available.

Are there significant enough RSVP, NSIS, etc. deployments where
specialized applications can actually make use of this?

Agree with Pasi on the example being invalid.

The example at end of Section 3 doesn't actually match the ABNF
syntax (it's missing a space after the colon).

I don't think the following BNF in section 3 is quite right:

   qos-mech               = rsvp / nsis / extension-mech
   extension-mech         = token

since rsvp and nsis are actually tokens according to the
IANA Considerations.  The intent is clear enough, so this
is just a comment...
