Now that creators can control player scales officially, it would be a wise idea to allow the player collider also.
World creators already have to opt-in to enable player scaling, allowing player colliders to scale with avatars/viewpoints will give a greater degree of creativity for creators.
An example would be
-"there's a vent short people can crawl into, but if you crouch, you can also fit." This prevents having to make wonky collider tricks to allow player exploration
  • "Tall players have speed that scales with their player capsule"
Etc
Just adjusting the collider opens the door to new creative social environments or games
For those who want to keep legacy colliders, make it an opt-in when enabling the new player Colliders and allow for the community to decide what they want
