Perhaps it is because I have used Linux for quite a long time now, and it did not always work so well, but I still smile when I plug my laptop (Debian, Gnome, Wayland) into a Thunderbolt dock via USB-C shaped connector, and its display appears on multiple 4K monitors within a couple of seconds.

I unplug it, and it comes back to the laptop screen.

Screen rotation on my laptop works flawlessly.

Thank you - genuinely - to everyone who has worked on making this happen so seamlessly.
