How about splitting LibreELEC into different editions like for example:
LibreELEC MediaCenter - for people who just want to play local and streaming content
LibreELEC Server - a dedicated mediaserver for Kodi/LibreELEC
LibreELEC Minimal - only what is really needed for running Kodi on top of a JEOS Linux
LibreELEC Legacy - for people that want to use their older PC/Laptop as a MediaCenter
LibreELEC Ultimate - containing everything which would be what we pretty much have now
