If your goal is actually to help insure the list have correct
information allow me to offer some advice:

Gratituious attacks on random groups of people followed by patronizing

Claiming that anyone who doesn't use a protocol is merely doing so because
they are a purist is not likely to give the impression that you are a
level headed reasonable person just out to contribute.

I believe that this statement is incorrect.  If you look at the history
of MPLS and its precursors you will see that improved performance of the 
the devices that run the network and hence the network itself was a goal.
I think what you want to say is that while that might have been a goal
at one time it is not the primary goal especially in the current

I think you are asking this because of Kav Salamatian's "full MPLS large
network" remark right?  I took his remark to not mean full in the sense of
deployed everywhere in the network but in terms of taking advantage of
most/all of the features that MPLS offers.  

As always YMMV
