You guys are saying "tryharders will find a way to abuse it" but I can't think of any way people could abuse start zones with this feature in a way that wouldn't be possible without the feature. It's just a quality of life feature, no more significant than using !teleport instead of waiting to hit the fail triggers.

If you're worried about people climbing on stuff, that's not at all an issue since the WRCP's already do that where possible (forbidden_tomb for example), and the velocity cap would continue to prevent people from doing it on stages that have climbable stuff that isn't used in the WRCP (syria_again final stage for example). Giving players the option to set a custom !restart/!teleport location would just make grinding WRCP's less annoying for everyone.
