Use cases I am more excited about:

1) Replace webhooks in web apps with wasm binaries provided by the customer, but that run in the web app servers.

2) Safer plugin system for professional software (plugins for photoshop, plugins for IDEs, etc)

3) Safer mod system for games and server-side mods that run on the game-maker server.

We had that in the 90's with Java. Why would this approach succeed today?

Why wouldn't it? It's a different technology stack, developed with the benefit of decades of additional experience running hostile code on the web.

		You mean like the CLR? Kind of strange that such experience still allows for WASM to be the target of C and C++ compilers, and there is no bounds checking support inside linear memory regions.

Check out https://extism.org, it is built for those kinds of use cases. However I think WASI and components could enhance it.

		sorry I meant "most excited about", WASI and components should be useful for the usecases I mentioned too. For example a SaaS services that accepts WASM plugins could provide a WASI that lets the plugin write to a object-store filesystem (like AWS S3) provided by the SaaS owner.

i had this same vision when i created hyper-mcp with modular plugin system via WASM plugins. Too bad, the community moves on from MCP to CLI with coding agent
