I think that BEagle and WWW are being a little over-cautious and over protective.
If you arrive IFR on the ILS in VMC at any medium sized GA airfield (let's take Biggin, Sa'fen' or LTQ as examples) you have a duty both to fly the ILS accurately and to take heed of the fact that you could be encountering aircraft turning from base leg onto finals at two miles, or joining from anywhere or even just passing quite legally through the ILS at four miles at 1200' without mentioning it to anyone.
If it is possible for an IR or IMC pilot to do this, it is possible for a PPL. The PPL isn't going to nosedive into a school just because he is looking both inside at the needles and out at the runway and circuit traffic.
As has been said, ATC will also know where most of the traffic is, including both circuit and ILS traffic.
