@MartinPavella @StrycekSimon I'm looking at optimizing out clones more aggressively from the graph during to_edge. I see that the NXP backend has some test coverage looking at clones in the context of the dropout op. Do you have any concerns with removal of clones from the graph? If not, I'm happy to take a pass at updating the tests accordingly.
