Describe the solution you'd like

I would like an equivalent of -D, --daemon Daemonize the Gunicorn process.

It would also be nice to be able to specify a log file.

If this were to be implemented, it should also create a pidfile to signal when the (main) server has fully started. This is used by service managers to find out when the service can be used (cannot be immediately after exec), and to kill it when necessary.
