I don’t see it as an overhead, I see using shell syntax as just another DSL like regex. There are many different use cases related to running processes—it is natural that different solutions may be preferred for different cases (check_{call,output}, with/out shell, run, Popen, pty/PIPE, threads/Asunción—all may be useful. And it is just stdlib ).
