Thanks for that work! deno_core is a beautiful piece of work and is still an option for OpenWorkers: https://github.com/openworkers/openworkers-runtime-deno

  We maintained it until we introduced bindings — at that point, we wanted more fine-grained control over the runtime internals, so we moved to raw rusty_v8 to iterate faster. We'll probably circle back and add the missing pieces to the deno runtime at some point.
