These things are on the roadmap atm.

Better WASM/JS interop is on the way, though atleast on Firefox nightly you can get this for fairly low cost for some functions.

GC is also on the todo list and IIRC might get an early preview in Firefox Nightly.

Once the GC is done, DOM integration will happen, people are eager for that and that would eliminate a lot of the necessary JS glue code.
