That all makes sense. The only thing I was missing was that this refers to power output. It seems like kind of a niche and tenuous value-add for a monitor. Why would I want to get power from my monitor?
Both at work and at home, I can plug in my monitor to my laptop with a single cable to my monitor. That single cable charges my laptop, connects the display, and passes through a usb hub that's built into the monitor that connects my keyboard and webcam. It's _incredibly_ convenient. It's also just a lot less cabling. You can think of it like a dock, built into the monitor for free.

Different workflows/circles. It's not something you're likely to use with a desktop, mainly with a laptop. It also really only works well if you use thunderbolt. It's reasonably common but probably not a majority where I work, where 90% of dev machines are macs.
