OpenRC on Gentoo works great. I have a full bleeding edge Wayland KDE Plasma with Pipewire setup that I game on.

OpenRC recently added user "units" aka services running as a user after a session start. Something that many new GUI user space applications rely on for various things.

There are growing pains. https://bugs.gentoo.org/936123

Especially when upstream hard requires systemd. More annoying when there's no real reason for it.

But there is a way forward and I highly recommend people try to build software to work without systemd before assuming it's always there.
