Your Pixel

Limited to Pixel 8 and newer devices and no 4k yet.

Oh, so your Pixel, but not my Pixel.

The 4 (iirc) also had USBC video out but google removed that functionality only to now have a reason to sell you a new phone. I hope its actually good and they publish source for it as part of AOSP, otherwise this news is fucking useless.

There were stability issues with the video out. People love to assume malice but most of the time there was actually good reasons

Thats nonsense, there are plenty of phones and tablets with usbc video output. Its been a feature for like a decade. Other companies have had working desktop modes for a long time and google just abandoned their work on it until they decided they could use it as a marketing feature. They probably just didnt want the pixel to cut into the chromebook marketshare.
