New Landing Pages for Word, Excel and PowerPoint (rant)

So I found out this week that MS is piloting new landing pages for the core Office apps (again).  Instead of loading in the M365 Home page, they now load in an entirely new page.

Why was this necessary?  We've already been here before and MS spent years moving everything to the Home app.  The dust has finally settled and things are working great.

Why move things out again?
