There’s also Strata, Niri, and to some extent Cosmic. My problem has been that they tend to be very opinionated and limited in the customization of the layouts. Having used XMonad for a long time, I may be a bit spoiled in that regard…
I do think there’s a middle ground for configuration without requiring programming skills, which can be off-putting for many users. After all, most layouts are just a combination of rows and columns. 😛
