From what I gather, when it seemed possible to link spherical deviation between Equatorial and Polar diameters with crustal evolution/motion of the Mid Atlantic Ridge via differential rotation, the community went berserk and tried to imply rotation as a factor without discipline or restraint.
Things have settled down somewhat for while it appears that there is a more reasonable approach to spherical deviation in terms of fluid interiors, the joined up thinking with plate tectonics and specifically the Mid Atlantic Ridge remains absent. The proposal for well over a decade is that there is a lag/advance mechanism which causes the symmetrical generation of crust either side of the Ridge based on an uneven rotational gradient from Equator to Poles -

It is always worth seeing researchers pull closer to a more productive approach to evolutionary geology via fluid dynamics or a round and rotating planet. It is just another instance where astronomy and terrestrial sciences mesh.
