This feature request is asking for:
The ability for users to set safety settings based on specific avatar stats, rather than the current broad "shaders", "custom animations", etc.
So for example: Being able to ignore lights and polygons for very poor avatars, but being able to restrict Texture Memory or Skinned Meshes to Poor or Medium.
This allows users to tailor their expeirences more to their hardware and what they feel is acceptable in terms of performance.
Bonus points for a "presets" system. The safety settings themselves could be converted to this system, where VRChat has presets for each trust level, and users can make custom presets for each trust level or globally.
