 Summary:
 Does GR have content beyond gravity, special relativity and E=mc^2?
Assumptions
1. General Relativity is the modern and most complete widely accepted theory of gravitation, formulated in a background independent, geometric way.
2. General Relativity is formulated in a manner consistent with Special Relativity and I could imagine that it might be possible to derived Special Relativistic effects from it (whether or not this is possible is beyond the scope of my question).
3. General Relativity is often cited as the source of the equation E=mc^{2} which can be generalized to:
(If these equations arguably has another source, this is beyond the scope of my question.)
Question
My question is whether there is any content or scientific law that General Relativity is the source of beyond (1), (2) and (3)?
Reason For Question
I ask this, in part, because it isn't usually called a "law of gravity".
My goal is to determine if I have some blind spot in my understanding of General Relativity and what it implies that I am not aware of, so that I know if there is something that I should learn more about to have a fuller understanding of General Relativity.
