Re: draft execution environment for WebGPU, including WebGPU env spec for SPIR-V

This document describes what security properties are desired In the "General WebGPU Environment” section, which is great. But it doesn’t appear to describe how a SPIR-V dialect can achieve these properties in the "WebGPU Execution Environment Specification for SPIR-V”, not even as TBDs as far as I can tell.

Is it it intentional that how to achieve security is unspecified?
