I suspect they'd prefer to sell you a new frame.
+1 On doing a cold re-alignment on the frame if it has no major issues having worked at a bike coop on a lot of nicer older steel frames, I have cold set the alignment and or rear spacing on 100 so frames without major issues. It is a lot easier if you have some frame tools and alignment gage, but I have done it with a 2x4 and a string fine.
