They certainly made it early on. It wasn't just Guggenheim that made the choice. It had been a collaborative effort on the part of all the creators. Even the ones that moved to Flash afterwards. Proof of this comes from the lack of a disconnect between the Olicity storyline across the crossovers. Most of the time, when there is a universe like this and two creators on each show disagree on a matter, you feel the disconnect on each other's shows when they reference the other.
