This has received criticism that a host-based model causes more signalling/reachability testing traffic than the tunnel-router- based one.

What's the basis for thinking this, and are there any good studies/ data to back it up? Intuitively, it doesn't seem like it should be so, to any significant degree at least.

Well, for one thing, a tunnel-router-based solution would typically cover some number of hosts.
