WASM / WASI could be a huge boon for plugins as it allows for code from almost any language to be executed in a secure, sandboxed way.

There is already the WASM Executor plugin, but we could potentially have built-in support for it and utilize WASM in several different places, including in the Controller and Server themselves, not just in ephemeral executors.

We could detect a WASM binaries on the filesystem and load them for different plugins, so a user could then have a custom image or volume mount with their binaries.

Implementation-wise, there do exist some great tools for this already, Exitsm in particular is an SDK for WASM-powered plugin systems and has an existing Go SDK.
