Dragging their feet and wasting time on garbage like "memoji" when they could have had this done with a reasonable amount of effort put into it, 3-5 years ago (even without the charging pad - that's just gravy).
I'm not even kidding. The software is almost all there too. Add mouse support to iOS, put out a wireless display/dock for it, and bingo.... pretty much done. Sure it won't be macOS, but for a lot of office users even iOS in that situation would be good enough. I know this, because I've done it, sans wireless display and wireless peripherals, for a year. I also gave it a go with an original iPad mini several years ago and it was ALMOST tolerable with a bluetooth keyboard for a lot of basic stuff back then.

Why?
For business/productivity use, airplay works just fine. Bluetooth works just fine for input peripherals and has done for a decade or more. It will only get better. And at short range (i.e., from my chair/desk area to my monitor) high speed high frequency wireless connectivity will make it more responsive.
Cords suck. With wireless, i wouldn't even need to take the ipad/phone out of my bag or pocket if it had plenty of charge. Just sit down at desk and work. Need to leave? No need to lock screen. No need to unplug, save work, power down, etc.. Just get up and walk out.
