In my book there is nothing wrong with leveraging procedures & practices (pre-heat, needle peening, run out tabs, post heat, etc, etc) that are obligatory to use in the repair of a much larger machine to do a similar type of repair on a smaller one. I think that it likely increases the possibility that the repair will live long-term.
Many posters have commented that you can’t just weld over the existing repair, so the question then becomes how best to do it in such a way that maximizes the chance of success. Like Dave I can’t see why that thought process should descend into a pi$$ing match.
