there are couple of things also

ie. wasm modules can be published and consumed to/from oci registries, which is nice

this linking is interesting also - ie. in docker you don't dynamically load other container to import functionality, but with wasm you can and because they're small you can architect your system around independent modules that use each other directly

they use nats for comms

and you can probably run your orchestrated system in browser - may sound silly but it's interesting capability as well
