Is there anything like this that can act as gadget devices for more than one host? (So I can plug it in to 4 different PCs or the like)

That's awesome. Do you recall the name?

I fail to imagine a usw case for that. Could someone enlighten me?

Part time “HPC”. Lots of bandwidth in usbc and probably just enough compute to use it. Testbedding comes to mind.

A debug port for an embedded device that looks like a UART and a MTP mount of the filesystem?

Nice examples. I suppose you could hang a Raspberry Pi on your smartphone, and have say a Kali machine on it. Though you can also run Kali on Android.

  [R]ecent update to the Raspberry Pi 4 bootloader
  (...) enables data over the USB-C port

Am I reading this right that RPi4 has five usable USB ports, i.e. unlike earlier models, port on bottom left of the board can carry data along with power? This is awesome!
