I disagree as to your opinions, which seem to just disagree for the sake of disagreement. The elements of Special Relativity were around. I stand by the assertion that someone else would have developed that theory within a few short years had Einstein not. And I stand by the assertion that General Relativity, had Einstein not existed, would have taken several decades before anyone would have fully put it together.

For anything Einstein is given credit for after about 1918, it was just the momentum of his popularity. Anytime another name is on anything, it is that other name that did most of the work, and because it was based on Einstein's earlier work, his name went on it also. And this is absolutely normal and expected in academia. Nearly all physicists do their life's work before they are 30, usually by the time they are 23. Einstein was nearly 40 when he published his Theory of General Relativity, and that is extremely out of the ordinary. You are seeing things, perpetuating the myth, when you place Einstein, the man, central to any breakthroughs after about 1918.
