All the formulations are correct.
"Relevantly similar" situations are more realistic than "exactly similar" ones, since they are closer to situations that we occupy in real life; this may be an advantage. To avoid controversies about which properties are relevant, we might switch all those that we even suspect may be relevant.

All the formulations are correct.
I violate GR consistency if I act to do A to X, believe that it was wrong for another to have done A to me in the past, and believe that the two cases are relevantly similar (believing that, because of features that they have in common, both actions fit in the same moral category).

This is our usual formulation. But the other formulations are correct too.
Correct variations on the golden rule require that we treat others only in ways that we're willing to be treated
All the formulations are correct and are provable as theorems.
