From my recollection (interviewed OTP team on this stuff once) they don't really intend to go there either. They are a very small team comparatively and maintaining that kind of runtime optimization would likely be unwieldy. (https://devchat.tv/elixir-mix/emx-114-just-in-time-for-otp-2...)

It won't be anything like V8, entirely correct, but it brings some VM code to native performance, beating NIFs in some cases.

I think some RabbitMQ tests reported 30% increase in throughput which is pretty wild.
