I love how people say "Face ID" and "notch" in the same sentence as if Face ID has anything to do with the notch.
The notch is there because Apple wants the edge to edge screen. There will still be a camera and depth sensors with or without Face ID, sorry. Therefor, there is still a notch. Unless Apple magically shrinks the technology, or goes back to larger bezels, the notch isn't going anywhere.
I do think they should also have included the Touch ID from the iPad Air, but that has nothing to do with OP's point at all.
