In this context WASM is more like a slower container than an application runtime. The potential advantages being:
* Far better isolation than a normal Linux container
* If WASM takes off, maybe architecture-independent artifact distribution
* If WASM takes off, maybe improved ability to call from one language into another
As a Kubernetes container runtime WASM today is probably most comparable to gVisor, with the somewhat huge caveat that it prevents you from just running normal Linux software.
