move to rust. I'm not sure you'd get much benefit from vulkan API
space or touching kernel interfaces as much. Granted a backend
compiler might be the easiest place to experiment.
I think the problem is you really want to justify that whatever you
introduce using rust is sufficiently better along any axis than c/c++
to justify the enhanced build time requirements and maintenance,
otherwise someone will just rewrite it in C/C++ to avoid having to
pull a rust compiler into their distro requires.
Note that Firefox already requires rust to build for three years [1], so any
distro shipping a supported version of Firefox has the rust compiler available.
The LTS branch of Firefox is currently at version 78 and thus requires at least
rust 1.41.
