Re: Wattage limit
They want to maintain the ability to run in power-restricted environments. Maybe it's also a principle thing as well. But imagine trying to run a raspberry pi powered robot off a USBPD cable rather than a mobile phone power bank. While not that many people use their pi for that, you'll see lots of plans and pictures in raspberry pi media, and it wouldn't be so impressive if it were handicapped by a wall connection. I would also say that a raspberry pi's utility to me has often been its ability to run with relatively little power; if I'm running something nonstop or off something with limited power availability, the pi is my go to solution.
