Thanks, Jerry. Don't get me wrong, I don't have (and never will have) a bike without scratches and marks. I ride all of my bikes and don't have and can't afford a show bike. So wear and scratches from honest, normal use is okay by me. OTOH, I would consider the use of nutted brakes on a frame designed for recessed brakes to be an interim measure, and as such there should be no evidence of it after it is rectified. This is sort of a sore topic with me because my 78-79 Colnago Mexico was built for recessed brakes but there is clear evidence of a serrated Campy brake washer being used in the past to span the recess to accommodated a nutted front brake. Since the fork crown is chromed, it is a permanent mark. I agree that it is not very noticeable, but I know its there and I can't help but wish the previous owner had taken measures to avoid this.

Well, I suppose if the bike were exclusively for show, this could be a concern. But a bike that is actually ridden will inevitably accumulate a few little nicks and scratches. A brake washer mark is going to be pretty minor and more easily touched up than the average small scratch. I personally wouldn't lose any sleep over it. Plus I rarely sell a bike anyway, so the problem would be likely to arise only after I'm dead.
Of course, if the bike is rare enough to keep only for show you're going to want correct brakes simply because they are correct, and wouldn't want to use an adapter to allow nutted brakes anyway.

The only issue I have with this method is that it will invariably leave a mark in the paint around the brake hole, which will be a permanent reminder that someone used the "wrong" brake bolt in the frame. If someone were to later rebuild it with correct brakes, the marks would be evidence of past abuse (similar to the aftermarket indenting of a chainstay to accommodate a "wrong" crankarm/chainring).

I've been following this thread wondering if this is really a problem. The recess is relatively short, while most of the brake hole is drilled the same size whether recessed or nonrecessed nuts are used. So if you use nonrecessed brakes in a frame drilled for recessed, the brake center bolt still is not going to move laterally. I believe all you need is a washer under the nonrecessed brake nut of sufficient diameter to cover the recessed hole and sufficiently thick that being supported only near its outer edge will not cause it to deform when the nut is tightened. In my experience the standard washers on Campy SP and Shimano and Suntour clones fit the bill, and there should not be a problem with using the nonrecessed versions of these brakesets in a frame drilled for recessed. The only potential problem I see is that nonrecessed rear brakes often use half-concave washers against the cylindrical brake bridge, while frames made for recessed rear brakes typically have a flattened center section of the brake bridge which doesn't match up with half-concave washers. Still, it just seems a matter of changing washers.

Rivendell Bicycle Works sells or at least used to sell a nylon bushing that neatly adapted allen mount frames/forks to nut mount brakes.
