Except… imagine the opposite paper cut - you are rebuilding surfaces and you always want say, a 5 by 6…
while I do not like the results here, I don’t see how it would be useful not to change the U as a ‘policy’. That would pretty much negate what Rebuild does - what if it were horrible?. There is RebuildUV, which while limited, might be the thing in this case, with a ChangeDegree to 5 in V after.
