Nessism- If the involved tubes were to somewhat evenly bend/bow through out their lengths then I agree that few would even be able to tell and that the tubes' integrity won't be "challenged". But I don't think this reflects how beams bend nor the changed strengths in the HAZ. I related my experience specifically to show this. That beams bend to a greater degree closer to the fixed end and that the strength loss in the HAZ, located right at the tube/beam end combine to make this end portion most likely to move. Remember that unlike a chainstay socket in a lugged shell, where the stay doesn't contact the other stay or the seat tube even, with well done miters the seat and down tubes do touch and have been brazed to each other. So the correcting isn't so much the shell bending but is the tubes doing so.

It is this reason that my first suggestion to Brandon was to get replacements, because if a tube did suffer localized collapse that was beyond his comfort level he had his next option on hand and could proceed right away. There's nothing wrong with trying to cold set the ST/DT angle. That's no different then raking blades, setting rear drop out spreads or aligning a built frame in general. It's just something that is best avoided (hence the build sequence advice given by some here for future frames) and also best understood of the possible consequences and how those consequences are valued.
