As VRChat has made their own components specifically designed for the VRChat SDK such as Physbones (to replace Dynamic Bones) and VRC Constraints (to optimize constraint behavior for Quest/Mobile users), adding onto the idea of VRChat creating their own cloth system I feel it might be worthwhile for VRC to create their own IK component systems akin to Final IK.

One of the main reasons being Final IK is a paid component that may increase the number of pirated copies to circulate across the community which could result in people possibly getting malware or violating Unity's terms of service.

Another is confusion of which version of Final IK version users have to use (current supported version is Final IK 1.9 from last I checked) and potential bugs that are left in the older version of final ik not being resolved.

Lastly, like many proposals previously, the idea would be to push this to make it more optimized for Quest/Mobile. More components that we use that are optimized for us to use on mobile, the better it'd be for everyone overall.
