Prefork webservers like gunicorn are usually configured to limit the number of requests each worker can serve, for various reasons. My model is based on similar motivations. It simplifies resource management and the scheduling logic, among other things.
So to be more precise, most of my processes are in fact set to autostart. They manage their own scheduling logic, and most of the cron jobs do `supervisorctl restart suchandsuch` which generally is expected to produce an error because the process will have exited normally at the end of the previous run. Perhaps not intuitive, and definitely not a complete separation of concerns as you point out, but I also don't see why I should reimplement in my own codebase what I have for free in cron.
