We've asked all customers, and nearly all of those have had us go ahead and filter it inbound into their tailcircuits. Some we're also filtering outbound, again at the tailcircuit. A few have asked for exceptions for some home or branch offices, but that hasn't gotten unmanageable yet. Most of the ones with complicated remote-access needs use GRE.
Yes, all people really need from the IPv4 global transport is the basic, transparent, end-to-end transport of packets with IP (not TCP or UDP) headers, without disturbing the TOS field...with that, we can evolve...
