Far more work. I wrote the X wm I'm currently using in a couple of weeks and it's a few hundred lines of code. You can get a working X WM in a few dozen lines or tens of thousands. Mine is ca. 700 at this point (floating+tiling). I considered wlroots but the complexity is far higher and Im not in a rush to move to Wayland.
