I agree that MPLS is not necessary for QoS if you have TE-aware 
routing protocols. There remain potential advantages to using MPLS, 
such as the various recovery and bundling mechanisms:

http://www.ietf.org/internet-drafts/draft-ietf-mpls-ldp-ft-02.txt
http://www.ietf.org/internet-drafts/draft-ietf-mpls-lsp-ping-00.txt
http://www.ietf.org/internet-drafts/draft-ietf-mpls-rsvp-lsp-fastreroute-00.txt
http://www.ietf.org/internet-drafts/draft-ietf-mpls-bundle-03.txt

The GMPLS extensions also provide a clean interface to 
non-packet-oriented transmission systems.

(G)MPLS is not a panacea,but it does have some useful functionality 
with which we are just starting to get operational experience.
