According to the spec, you're right

>https://specifications.freedesktop.org/wm-spec/1.3/ar01s03.html

> This property MUST be set by the Window Manager upon calculating the work area >for each desktop. 


What real-world problem were you hitting?

It was reported by one of my users:

I rely on this value to display animations based on user multi-touch input. You can see some examples here:

It was easy to workaround on my side though.
