my take on this that we are talking about "extensions" relative the
the existing specification, it is quite possible for an extension to
leave "components of the MPLS architecture unused", that is in
fact the case with most of our documents.

Consequently I agree with Stewart, and would oppose words like,
reduce and modify, since that implies that we intend to *change*
the MPLS architecture, while one of the foundations of the
agreement to create an MPLS TP was that it should fit into the
MPLS architecture.
