The point being, the General Relativity allows for such interpretation, not whether there is any need to do so.
I agree that complex scenarios emerge when acceleration is not constant. Likewise when loose objects are acted upon by a changing gravity field. Do we need to discuss them, to further condemn Luther?
There might be weak vs. strong equivalence principles in play, but to do so I need to refresh my knowledge of physics, which is nearly as old as Carl Sagan.
I didn't bring up the subject of reference frames. That was you. If you are saying that you no longer what to discuss the subject--which also includes objects that are accelerated by other forces than gravity--fine. As for Luther, I am not intetested in condemning him. This isn't an Inquisition. It is a discussion and disputation of ideas.
