Tell me if Im wrong but I guess that the dominant client layer of, for example OTN, is MPLS. If one solves the MPLS case, then one solves the OTN case for a dominant proportion of OTN cases. On the other hand, if one solves timing over OTN without using the MPLS layer, then one does not need to solve how to carry time over MPLS whenever layer 1 is OTN.
More and more networks are built with DWDM optics being put directly into routers/switches, ie no OTN at all. Future framers might be switchable between G.709(with FEC), 10GE WAN/LAN phy, and other framing standards, but this is not the case today.
So any packet standard addressed by this WG should look at doing the standard over packet (and not just MPLS, it should be over IPv4/IPv6 which might be carried by MPLS, but this should not be a requirement).
