> Excluding graphical APIs, the basic stuff (file IO, networking, etc.) isn't all that hard to add to a language (it of course depends).
You could implement a modern graphical API on top of virtio-gpu, which would give you low-level access to accelerated graphics.

Some uses of mmap and shm actually seem to have a near-equivalent already in plan9's segattach. Other uses would require some implementation of distributed shared memory (i.e. implementing the usual CPU concurrency model over the network) to be made feasible while keeping to the usual networked-OS focus of plan9.
Right, you could do it... maybe. Some languages/libraries/runtimes could have specific expectations around the specifics of mmap that can't easily be papered over, but I suspect it would be a minority of cases
