To each their own. But I must point out, every edition change and setting update is an exercise in cherry picking to some degree. It is inevitable.

An update to Spelljammer - or whatever they call it - could include multiple presentations on a "solar system," for lack of a better term. The book could provide a discussion and diagrams showing how it could work in a heliocentric model, in a geocentric model, possibly a Pythagorean model (both the Earth and the Sun orbit something else at the center of the universe, and maybe even a psuedo-Greek model (with Apollo and his chariot function as the sun).
