This is a common framing of the Copernican revolution, and it's wrong.

Copernicus was proposing circular orbits with the sun at the center instead of the earth. The Copernican model required more epicycles for accurate predictions than the considerably well-proven Ptolemaic model did, with the earth at the centre.

It wasn't until Kepler came along and proposed elliptical orbits that a heliocentric solar system was obviously a genuine advance on the model, both simpler and more accurate.

There was no taboo being preserved by rejecting Copernicus's model. The thinkers of the day rightfully saw a conceptual shift with no apparent advantage and several additional costs.
