The other role an #init process can provide is to install signal handlers so signals sent from the host can be passed onto the container process. PID 1 is a bit special as it requires the process to listen for a signal for it to be received.
If you can install a SIGINT and SIGTERM signal handler in your PID 1 process then an init process doesn't add much here.
