There's no recommendation in my opinion, it depends what the user wants in the window manager. A window manager has two functions: Layout and control. It's how you implement those that defines the philosophy of your window manager. This topic goes deep, you can take a look a this research paper or this article/podcast

Your window manager will support wmutils if it's written for X11, there's no other requirement. Maybe some functionalities like the changing of borders may not work if you redraw the borders within your window manager. As for xdotool, it's mostly the same, your X server implementation should come with the XTEST extension, which mostly always do these days. There's some features within xdotool that require you to implement some EWMH (Extended Window Manager Hints). You could check the specs for more info: https://specifications.freedesktop.org/w...atest.html

Being lightweight while at the same time allow composition. Things like zooming. Good support for EWMH also.
