I understand why VRChat capped height to 5 metres. In public instances, any larger would leave so much room for mischief. However, it would be nice to be able to go bigger in controlled or moderated instances, especially with this post: https://feedback.vrchat.com/open-beta/p/1833-custom-avatar-scalers-broken
If the instance master could set the max height, overriding the world, I think that would be a happy medium.
