Yup, came here to mention PaperWM. I used xmonad in the past, but I executed it on top of Mate to have an “easy” desktop environment.

Nowadays Gnome extensions providing tiling is the equivalent “easy” method. Gnome is not for everyone, but it works out of the box- then you add the fancy tiling window management on top.

For people who have bounced off systems that require much more set up, I think they are a good option.
