Before Project Reunion came to be, Office team was starting to adopt UWP.

See BUILD recordings from 2018, I think, where they demo the new UWP controls contributed by the team, similarly to what happened before with the ribbon on Windows 7.

I would vouch they got as happy as the rest of us.

Those versions in the Office store are d.e.d. Except for OneNote for Windows 10 which is shortly on it's way out.

Yes, because of how UWP and Project Reunion went down, right after they started looking into it.
