Once out of beta would vrchat still be open to expanding the suggested collision tags? And if so would it be from canny posts, or when they think a tag is popular enough. with contacts being added to worlds the standardization for tags I think is going to be getting a lot bigger. especially if people design systems that use a bunch of specific tags.
To take some of the load off of vrchat, having a way people can either create their own tag list or download a list by someone else. and have it show up in editor would help making standard tags people make easier to use.
