Calling out and criticism is fine! But to answer your question: for the foreseeable future, our "metal" is JavaScript, so that's what we will be finding ways to expose. We have already designed our stack mechanism to enable decent JS interop (e.g., no CPS). We want to make it possible to import JS libraries without hurting security, for instance. We've got some students right now working on integrating graphing and other functionality that we'd like to make widely usable.
