At the very minimum, omarchy and omakub already provide out of the box seamless fixes for all the common issues that are “fixed” but need tedious involved configuration nonetheless.

Honestly, given my experience from distro hopping, I am certain that collecting solutions across distributions and implementing them in one can go very far. It's almost as if distributions contributors too rarely try out other distributions to then steal what the other distribution does better.

Small enthusiast distributions with a bit of a hype can gain good features in by just pulling in knowledgable users missing things from their previous distro - and they can move a lot faster than the Debians or Fedoras of the world can, no committee decisions to be made first.
