Quick note: I looked at the bindless proposal linked from the blog post and their description of Metal is quite outdated. MTLArgumentEncoder has been deprecated for a while now, the layout is a transparent C struct that you populate at will with GPU addresses. There are still descriptors for textures and samplers, but these are hidden from the user (the API will maintain internal tables). It's a very convenient model and probably the simplest and most flexible of all current APIs. I'd love to see something similar for WebGPU.
