Is it project maintained?

The idea is brilliant, shocking for me there is no tool to code generate JS bindings of a go wasm package, such was-pack for Rust.

I am afraid there is no intention to be a full feature toolchain?

...I actually missed this even being asked. It was a fun side project but hasn't gotten a lot of interest, so I've kind of let it slide. I'm open to taking it back up if there's interest.

I'm certainly interested — being able to build a state machine once, and have it usable in many places with the type safety of protobuf would be extremely useful!

Would you be interested in picking it up again? I might try and do so myself either way; I'd definitely be interested in whether Go (and TinyGo!)'s advances would have helped with the speed problems you mentioned.
