Not to denigrate your work, it's good what you're working on... but I can create JS APIs in Rust with native V8 bindings, too: https://github.com/denoland/rusty_v8/blob/main/examples/proc...

After working on a couple codebases that used wasmtime and wasmer heavily, I think if I were to start from scratch I'd just use V8 as my WASM runtime.

(And the model I would follow would be to containerize the V8 runtime piece inside its own cgroup, with resource budgets and permission constraints. cgroups accounting beats the limited and inefficient accounting one gets from the various WASM runtime opcode based accounting systems.)
