I would not consider Manjaro too big to fail considering what they're currently going through. The distro has been stagnating the past few years tbh. The community wants collective ownership but the founder is stalling more time. If you're curious they made a big post about it on their forum. Not a Manjaro hater btw its was my first distro that got me into Linux and now I just use mainline Arch. I liked the config, look and feel and polish it provided. If I started today I'd probably go Endeavor or Cachy probably.
