I think the argument will be around the hole area of whether gravity is actually a "Force".
Einstein works in certain conditions and Newtonian theory works in others.
In geophysics we use Newtonian (and only a wee bit of quantum) theory because the "force" is applied mostly to static or slow moving large scale systems" in non-molten conditions
Things like gravitational constants and gravitation equations are all useable and they WORK.
We could be all qet but in a systematic fashion that we have one of those field equations upon which we base a false technology. BUT until someone disproves it, Im still hiring out consultants and grad students to do gravitational surveys for mapping of ore bodies and hydrocarbon reserves
