The reddit post you linked just proves the point that there seems to be no real plans for Cinnamon to support Wayland, so it doesn't make much sense to adopt that DE now when X11 is slowly dying.
I don't conclude that it proves anything. It just states why you might have reason(s) for holding back. Cinnamon shouldn't be dying. The defaults of xfce are quite old-fashioned. whilst Cinnamon can easily replace Mate and Gnome. I think they been doing some work with xapps, hypnotix iptv and web-xontainers to launch programs
Whilst their radio player works in the same way as internet radio for gnome and rwall works in the same way as the random wallpaper extension pulling in the same sources even.
Cinnamon is described as "Linux desktop which provides advanced innovative features and a traditional user experience".
whilst xfce is described as lightweight and modular. Xfce is probably easier to begin with. But Cinnamon seems like the most obvious choice for a mate replacement (xfce never had the same roots). and there's plenty of xfce out there already MX, Manjaro, Zenwalk, debian to some extend as it was always the way to go if you'd install from a terminal with a bare system, Void etc.
I can respect the decision but disagree with the process that led to the decision and the reasoning.
And as I'm not a developer in anyway I can only posts my views post the decision has been made. Otherwise one would have to be psychic. While I'm open minded by nature that's probably not the most common trait.
