What is the relationship and support level between ProjectReunion and WPF?

How does Project Reunion relate to WPF?

Issues are being raised showing things don't work with WPF (examples: #437, #593) but the responses leave it unclear if they are supposed to (yet?).

Is there, or will there be, a point where you'll be able to say "WPF is officially supported by Project Reunion" ?

Are there plans to clearly document which parts of Project Reunion can be used or consumed by different frameworks? - I understand the high-level vision of "anything can use any part of Project Reunion" but the reality is that isn't the case, won't get close for some time, and there will be parts of Project Reunion that only work with WinUI3.

With WPF & WinUI3 being roughly comparable but WinUI3 being treated as a core part of Project Reunion (in interpretation if not intention) what does this mean for WPF? Will WPF later come more closely under the ProjectReunion umbrella too? If not, what are the plans for their co-evolution and collaboration?

The roadmap is very vague in its references to WPF. It says that WPF as a packaged desktop app has a number of items "you (tentatively) can expect" but then shows a table containing things that do not relate to WPF. At best this is confusing and open to wide interpretation.

The WPF GitHub repo has no mention of ProjectReunion 😢

So, can someone from Microsoft please clarify?
