BindGroups being a hard to fix design wart is true indeed (which I have been complaining about pretty much from the beginning, not because of the performance problems - which surprised me too - but because of their inflexibility compared to a traditional bindslot based model like in Metal1 or D3D11).

But I would prefer to first bring the peformance of the slot-based binding model to a point where it is similar to D3D11 or Metal instead of ignoring that part of the API and 'skipping ahead' to bindless (which will probably have to be behind an extension anyway). Otherwise WebGPU will become a cemetery of abandondend attempts like OpenGL.
