I imagine feathering was mostly done after the fact because otherwise the lug would be hard to braze.
I remember reading an account of someone who was replacing a tube on a damaged frame with very thinned lugs, and when they hit the "lug" with the torch for a couple of minutes to loosen the end of the tube, most of it disappeared. You see, most of what the builder left behind was just silver brazing material where the lug had once been.
