That&#x27;s certainly true today, but other ecosystems have benefited tremendously from tools that are able to work directly with the IR (well, bytecode). Usually to pull off features that can&#x27;t be expressed directly in the language without huge pain, like continuations, or to do things like profiling.<p>I understand the desire to keep MIR private and avoid needing to stabilise a syntax and feature set for it, but there are benefits to doing so as well.
