I switched to KDE on Debian after using Windows for the last 10 years. There's a fair number of very minor bugs, not to mention things that might be bugs or might be design choices that I don't like. But all in all, I'm very happy with it.
Announcing this on april first makes it difficult to parse if this is a serious proposal or not. It appears to be, but maybe i'm missing the joke.
Personally no experience with kde plasma, but i'd love something more usable than gnome 3. Mate/xfce are my go-to options when they aren't completely broken as shipped by a distro.
Ahhh. It seems to have a timestamp thing at the very top of the post, to the extreme right of where it says "Joshua Strobl joshstrobl Packaging Team".
That presently has what's probably an edit count "1", then to the right of that is the timestamp. For me, it's currently saying "19h".
When I hover the mouse over that for a few seconds the tooltip pops up with:
2 Apr 2024 19:40
That's pretty likely the "official" submission date, no idea which timezone it's in though. Could even be localised to whatever timezone the viewer is in. :)
KDE has far too much surface area to test and support (as in end user support) effectively. Gnome may not be as flexible but it makes for a much smaller target to be able to reproduce and triage issues.
If people want KDE they can install it. Making it the default is short sighted and doesn't align with, or help further, the goals of the Fedora project.
