As Ubuntu 20.04 has been out for a while now, I wonder when it will come to the OnePlus3. Unfortunately, on the device page, I cannot find any related information, and when I click on "report issue", I am redirected to a Github repository for Halium for the OnePlus3 with no obvious connection to Ubuntu Touch. Is this device abandoned?

@thilov Actually, with regard to Linux smartphones, it clearly does mean that the phone can convert itself into a full desktop computer when connected to a full display & keyboard. That's also how it is being described on the Ubports website. And again, with my pinephone it works: I plug in a USB-C port and everything connected to the USB-C port - display, keyboard, mouse, ethernet etc - becomes available. I don't know whether it works with Ubuntu Touch on the pinephone, its support of the PP hardware looks incomplete for now. But with other distros, it does work.
