Indeed. This is why Laurel never was affected by the particle accelerator to begin with when she became the Black Canary. Because it wouldn't make sense on Arrow. Same reason Vertigo became a drug on the show and not a superpower and Firefly is a vengeful firefighter and not an arsonist on a jetpack.
