Honestly for the best lol.
Jokes aside, I don't see why this would exclude those languages. Just because they need a runtime doesn't mean the runtime can't be bundled (even if it is annoying to do so). I would imagine for runtime-dependent tools, they would just make a generic runtime bundle that can be shared between packages, similarly to how it's done with flatpak.
I think "tools [bundling] all their dependencies" is more likely to mean that you need to ensure that third-party libraries your tool depend on are bundled, which is good. End users, even if they're developers, shouldn't need to hunt those down just to use something.
