Why would an exploit be toggle-able though? It's a bug, i doubt there's much control over how it works, so i don't think it's very possible nor necessary to have it be an optional thing
It should just be fixed and anyone who wants to climb walls can use one of the many add-ons that allow you to climb or move on walls
People who don't want their builds exploited shouldn't have to place a dozen of invisible ramps on every roof as there's still cases of it getting in people's ways with lower and more accessible roofs or unbalancing or ruining certain rooftops because people can stand on top of these ramps
People who want to use a bug as part their build shouldn't complain when people say they want that bug rid of, it's a bug, something that shouldn't be in the game, something that only benefits a very small amount of people, especially in a way that can just easily be replaced with even a single add-on
There are bugs/exploits that can be fun, but some are less exploitable in bad ways than others, but you shouldn't make a bug a part of your build and expect it to never be fixed or complained about when it starts being used for bad reasons more than good, because once it does get removed, you're gonna have to find a way to readjust your build or be stuck with nothing
In the end, it's more trouble to keep than it is to get rid of, there's no reason to argue about this, it's easier to use an add-on or not have builds have parts centered around an exploit than it is to unnecessarily increase your brick count or make your build harder to use or navigate just because people love to cheat and get unfair advantages however they can
