For example, in one of my projects, I want to run a particular stage only if rust = nightly. Currently though, language-specific configuration parameters do not seem to be available (at least, I never see them match).
Never mind, I misunderstood how stages work. You don't match on existing matrix entries, you create new ones. So matching on configuration (like os) makes no sense.
