The shell also supports shell scripting! You don't need Just or Make Especially for Github Actions, which is stateless. If you want to reuse computation within their VMs (i.e. not do a fresh build / test / whatever), you can't rely on Just or Make A problem with Make is that it literally shells out, and the syntax collides. For example, the PID in Make is $$$$, because it's $$ in shell, and then you have to escape $ as $$ with Make. I believe Just has similar syntax collisions. It's fine for simple things, but when it gets complex, now you have {{ just vars }} as well as $shell_vars. It's simpler to "just" use shell vars, and to "just" use shell. Shell already has a lot of footguns, and both Just and Make only add to that, because they add their own syntax on top, while also depending on shell.
