Not true, a lot of mathematical problems behave better (but other semiclassical approaches also exist).

As for the epicycles comparison, it's actually apt. They could have given complex plane and Fourier analysis for free if they had a chance (not to mention Copernicus actually used more of them than Ptolemy)(which incidentally is also the case with Many-World-necessiated landscapes and parameter spaces - just as much additional layer but with additional problems that are, in contrast, untractable by current math).
