Just out of curiousity, do people here have non-business-related need for GHA? I've never really seen the use of it for anything I wanted to make on my own time; it's more than easy enough to run tests locally, even on my 12-year-old office desktop. (I'm only using it implicitly because it's how the blog publishing system works under the hood, but the SSG still runs locally.)
