I've only come across this recently, but I'd love to be able to animate perspective correction on and of with a slider. I've recently had to match some renders that were made with the standard renderer with ones made with Octane and Corona that had perspective correction on, and it's proven quite a headache to get them to match up... currently the only solution is trying to hide it in a fade or jump cut, but being able to animate the correction on or off would be super helpful.
Obviously, this is probably low-priority, but I'm posting on the off chance that it would be easy to fix/implement.
