I completely agree! The main issue is that this will require some deductions first. Standard books like Physical Geodesy by Hofmann-Wellenhof & Moritz (2006) don't have the equations. There is an equation for the gravitational potential but they take the derivatives of it after adding the rotational term. So we'd first need to do the maths of deriving the equations. See #151 for references.
