I seem to think I've seen people doing this at most exchanges ISC has
installed an F-root node at. The motivation is usually the avoidance
of either expense ports on exchange switches, or the avoidance of
expensive ports on routers (trunking the IX in as a vlan to a router
on an existing port).
I'm not saying that the practice is good, or recommended, or without
peril. But it's certainly not isolated to the UK.
