This bullet point from the reason to chose one library over another is a prime example of what I love about XFCE:
• smithay has great documentation.
Not only are they considering it, but they're expressly calling it out. I'm convinced that the publication of the Agile Manifesto was an exercise in Cunningham's Law, and to that end the XFCE team has produced something great by doing the opposite.
