Good point - this is indeed better than the absolute first-hop-router.

Actually, I've been thinking more or less along these lines anyway, for
exactly the reasons you list; I just used the phrase "first-hop router" more
to indicate that it was _close_ to the edge, as opposed to in some vague
'core' (e.g. at inter-ISP boundaries, or something like that), rather than to
indicate that it _had_ to be in the _very first_ router.
