The Slackware folks have it working, but non-systemd distros are going to need to find a desktop they like and work on it, same will apply to wayland. If a distro doesn't want to use modern Linux tech they're going to have to put in the work.
I've already passed along the Slackware patches to our GNOME maintainer and he wasn't impressed. And that's about all the effort I care to expend, since I wouldn't be caught dead using GNOME. It's not for me.
That's fine DE's are personal but the larger point is those distros that don't want to adopt new tech need to start creating and maintaining the things they need to operate. The contradictory path is hard for a reason.
It's technically possible to get GNOME 49 working without systemd, but it's merely kicking the can down the road.
The reality is that work has to be put in to support non-systemd paths. If nobody does that, well it has to be dropped.
If opensource were generally paid, there would surely be devs working on non-systemd support in GNOME.
