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

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.
