Also one of the few OSes that was already "WebAssembly" everywhere back in 2000.

It is called language environments.

IBM i and Unisys ClearPath MCP (nee Burroughs) are two other examples still being comercialized.

All the ideas that many folks sell as being invented by WebAssembly were already present in such systems.
