Ours supports this feature as well.  So does Cisco and Juniper.

My only point was that I know of no one that is building a network
using statically configured LSPs.  The assumption was made by Dave
that the opposite was true.  I was just commenting on the validity of
that assumption.

Providing measurement capabilities to better deal with rare errors
that may be undetectable when using an unused feature sounds like a
weak argument.  I suppose it would be up to the TE-WG whether that
constitutes a requirement.  In the ITU maybe.  :-)
