Very cool! As a wasm fan, I'm excited to see this and really appreciate the detailed write-up. As a maintainer of Extism[0] (a wasm plugin system framework) I'm curious if our project came up in your research for this, and if so, what is missing or kept you from considering it as a solution?
I'm pretty sure our plugin system predates your project (it's been around since before our beta was released in 2021, we've just given it the attention it deserved right now).
I'd definitely have wanted to outsource this though if we didn't have the infrastructure in place already. Extism seems solid.
