Sure, but realize that there are limits on the improvement of basic LISP
handling.
E.g. if we allocate a large number of PI blocks from a large EID block, an
ITR will likely _still_ have to do a mapping lookup cycle in order to be able
to forward traffic to an PI EID block's ETR. (Since there would be many
different PI blocks allocated from that large PI block, scattered all over
the Internet.)
Yes, the 'interoperation with legacy hosts' part would be better, since there
would only need to be a single large advertisement into the legacy DFZ (as
someone else pointed out).
And who knows, maybe someone will develop a use-case in which 'facial' EIDs
bring more significant benefits. But I think Darrel's point is very accurate:
"we should keep our expectations for the benefits of this block modest".
