Unlike the elaborate but contrived scheme of Newton, the early 20th century theorist looks crude -

There is little or nothing to say about the relativity nonsense built out of Newton's absolute/relative 'definitions' as the damage has already been done centuries before .

It is unfair to say that it comes down to an attempt to use RA/Dec to obliterate the Lat/Long system or rather try to bypass the central Sun and appeal to a rotating celestial sphere however it is a major issue which the empirical drones here wish to maintain.

The Lat/Long system is built into the facts of a round and rotating Earth -

Over the course of an orbit the surface point where longitude meridians converge will be seen to turn parallel to the orbital plane unlike diurnal rotation which does not. It is the forward motion of the Earth through space which causes the single surface rotation to the Sun and because the Earth's varies in speed this orbital surface rotation responds in terms of the natural noon inequality when combined with diurnal rotation.

The disaster of RA/Dec reasoning, if it can be dignified as reasoning, is the willingness to impose rotation directly into the celestial framework even though the Lat/Long system would prohibit such a drastic action.
