"Relativity never claims the speed of light is the same in every frame". Well, under some specified conditions, not involving accelerations/decelerations it actually define it. When it comes to accelerations/decelerations you can still argue that the discrepancy you measure (from 'c') is a result of 'gravity', locally measured. There are two sets of relativity, one being SR, the other involving gravity (GR). And using SR 'c' is a constant.
"It is the independence of the speed of light from other objects in motion that I believe needs a good solid mechanical explanation."

I don't quote-mine, I educate. For example, see this Wikipedia article:Robert B. Laughlin, Nobel Laureate in Physics, endowed chair in physics, Stanford University, had this to say about ether in contemporary theoretical physics: "It is ironic that Einstein's most creative work, the general theory of relativity, should boil down to conceptualizing space as a medium when his original premise [in special relativity] was that no such medium existed [..] The word 'ether' has extremely negative connotations in theoretical physics because of its past association with opposition to relativity. This is unfortunate because, stripped of these connotations, it rather nicely captures the way most physicists actually think about the vacuum. . . . Relativity actually says nothing about the existence or nonexistence of matter pervading the universe, only that any such matter must have relativistic symmetry. [..] It turns out that such matter exists. About the time relativity was becoming accepted, studies of radioactivity began showing that the empty vacuum of space had spectroscopic structure similar to that of ordinary quantum solids and fluids. Subsequent studies with large particle accelerators have now led us to understand that space is more like a piece of window glass than ideal Newtonian emptiness. It is filled with 'stuff' that is normally transparent but can be made visible by hitting it sufficiently hard to knock out a part. The modern concept of the vacuum of space, confirmed every day by experiment, is a relativistic ether. But we do not call it this because it is taboo."
