1. We can do the same by sharing subresources.
2. Shared parts can be optimized to instanced drawing by the client. This would
   also only be a bandwidth optimization, avoiding gigantic prefabs.
3. KTX is worse then WebP in terms of size. Transcoding on the client is
   possible.
4. Automatic atlas packing is also possible on the client.
5. Introduces too much complexity and interfers with our animation system.
