First look at the first PinePhone keyboard development units, these have some mechanical issues, and the pcb design might not be final. But at least some keypresses work :D
They could have included a Thinkpad like nub, but I think there might be patent issues.
But from the comment in the video it sounds like internally the keyboard addon uses a keyboard and trackpad circut, so maybe it could be hacked later on.
As for additional addons: those use the same 6 pogo-pins and I could imagine that ends up a bit bandwith limited unless it uses some sort of standard like USB2.

I recall almost all laptops had those at some point. IBM must have been making some good money off of that if that is the case.
From the Pinephone wiki:
so I2C, but no USB data unfortunately. But hey, it’s not like a sensible linux distro would not be capable without a mouse!
