I think the applicability statement should *not* be limited to only what's
already implemented and tested.  

According to the TEWG charter, "[the tewg documents] ISP uses, requirements,
desires (TEBCPs)"

Current operational TE methods are limited to what vendors are offering,
which right now are rudimentary capabilities for TE.  Therefore, the
TEWG/carriers are specifying requirements for TE methods that they feel are
required/desired.  Such required TE methods can only become operational when
vendors implement the features recommended through standards.  

I'm not aware that vendors already offer, and carriers already implement,
the TE features needed to fully support provisioning, measurement, control,
routing, resource allocation, design, and operation of MPLS/TE networks.
