One of my sus forks had exactly that setup. Instead of three holes covering an arc, there was a rather minimalist design with only one hole in a slender tab protruding from the brake anchor plate. You positioned the tab, torqued the removeable brake boss and you were done.
I had no issues with that feature as such.
Only thing was that on that particular design, there was a hexagonal base to the brake anchor plate(probably to ease positioning), so the plate got fairly thick, and the brake ended up some 10 mm further out than on the previous fork. Not a disaster, but not ideal.
