But different mechanisms nontheless. You claim
that different mechanisms will be affected in
different ways.

If you are unhappy about the fact that particles
are involved, then add to the list the observed
spacetime effects noted in systems consisting
of spinning pulsars and closely orbiting massive
bodies.

The properties of spacetime as observed.

Besides, physics is not about causes or "why's".
Physics is about creating mathematical models that
accurately predict what can be observed. Relativity
is such a model, and works beautifully. Can you
find a single instance of a prediction of relativity
that has been falsified by observation?
