While I may have an opinion on whether these functions offer any
practical benefits, from my point of view it would be more important
to get the opinion of the folks who actually use this in the
operational environment.

With this in mind, I'd like to hear comments from the folks *who
have operational experience* with MPLS on whether the functions
you mentioned above offer practical benefits.
