Why is postmarketOS SXMO a good choice for Pinephone keyboard users?

Last Updated on October 21, 2023 by pg@petergamma.org

Is this because Pinephone developer Martijn Braam uses postmarketOS SXMO?

And is postmarketOS SXMO the only Pinephone distro which can do the following great things with the PP keyboard:

the keyboard works perfectly out of the box.
Alt G gets you the third layer symbols on the numerical keys.
The Pine key & numerical keys gets you the function keys.
No mods of any sort required.
SXMO makes out of the PinePhone essentially a phone which runs a terminal with menus and gestures.
