Clustering requires "live" in aliases array

We do not want the rtmp application "live" to be accessible, instead we only want private secret name. Clustering requires "live" to be in aliases array otherwise nothing will work and there will be rtmp errors on the 1936 listener (asking for app live which isnt there). Isn’t there a way to use aliases[0] for clustering app name? Rather than rtmp with hardcoded app name ? Why does clustering require an app to be accessible at all, actually ? It’s on a different port and everything.
