Our tunnel code typically processes tunnel packets upon receipt at a single
address (/128 for v6 or /32 for v4). This is by far the easier and more
"normal" way of doing things for the myriad of tunnels we support today.
Implementing on receipt of anything other than an address (or hostroute, if
your prefer since this is a router) is "possible" but would certainly be
considered "special" and as such has a higher bar for implementation within the
typical tunneling architecture (at least in the implementations I am aware of,
YMMV).
Apologies if I was not clear on this point when we talked the other day.
