I know that 'set view' is not for avatar scaling, but there's many users want use set view to avatar scale.
The warning in the screenshot appears to be, 'We never intend to formalize this function.'
If developers make this feature official, many users will not have to upload other avatars to change the size of their avatars.
This will be very convenient and will prevent the indiscriminate increase of avatars within the VRChat server.
I don't know the IK mechanism that VRChat uses, but I think you can create a program that recalculates IK based on the distance from the origin of the avatar to the head.
thank you
