I'm sure this will look just as natural as the non-Chroma Keyed background obfuscation/picture injection from Teams.
Where ears and the sides of your head get cut off when you turn your head and if you aren't fully bald or with a full head of hair... all sorts of weirdness is going on above you.
Awesome.
Oh and to answer your question on why... this is because with everyone WfH, they've come to realize that it's actually hard to talk TO a camera while trying to NOT focus on your return video feed or any number of other distractions going on. :)
