Could you provide some context on ShadowRealm? Is there an issue / PR about this?

It’s a JS API proposal that’s currently being worked on: https://github.com/tc39/proposal-shadowrealm

Unlike most new JS APIs that Deno implements automatically because they ship in V8, this one requires some work to support in the internals of Deno. You can follow the work at denoland/deno#13239 (although the work recently had to be rolled back in denoland/deno#16366 because it was blocking certain refactors; it should hopefully be relanded in a couple weeks).

However, vm needs some more support in deno_core (and maybe deno_runtime) than ShadowRealm needs, because you cannot cross objects across the realm boundary with ShadowRealm but you can with vm. This would need a lot of checking that everything is handled correctly, and that certain realm interactions happen properly, that wouldn’t be needed with ShadowRealm.

Oh never mind, I found https://github.com/denoland/deno/issues/13239, which is an issue tracking support. Linking this here for future reference.
