I love to see the occasional flexbox appreciation, since at least for me (someone just getting into Design/Web dev) flexbox changed responsive design from being a totally unfeasible project to being genuinely fun to work on, and sometimes the most exciting part!
Fedora uBlue user here. I’m happy sticking around until I see signs of IBM’s changes affect upstream fedora. If it happens, I’ll be moving over to VanillaOS or OpenSUSE Aeon, but right now, the changes seems to be isolated to downstream RHEL.
