Yes this is true today but dont forget that linux is just generally slow. As each app is a docker there is one day the possibility of someone rolling all 4 or 5 apps into a preconfigured single docker or app that can be a one click install, easy to use. It just hasnt happened yet due to time/lack of effort and so on. Open source is slow like that. Its a voluntary thing so these things always take years.
It is awesome. Whichever country develops it first will be remembered as the next ‘moon landing’ event forever.
