VRCSDK provided a built-in Global Collider feature with the physbone collider component in the SDK 3.10.4 update, which works exactly the same as that of fingers and hands: https://creators.vrchat.com/releases/release-3-10-4
With this, it is able to 'add' up to 4 global colliders without needing to hijack fingers' colliders.
The suggestion is to use this feature as a priority, and use the hijack method as a fallback when the current SDK is not supported, or the number of extra global colliders exceeds 4.
