official way to manipulate GPIO pins
I didn't find an official statement.
I did see an interview with Eben Upton and he mentioned libgpiod but I can't find a reference for that.
I did find the following which shows libgpiod and gpiozero working on Pi 5 and rpi.gpio is said to not work.
I did check to see what came installed on my Pi 5 with Bookworm and here's what I see:
$ apt list | grep gpio | grep installed

Note that 'installed' doesn't necessarily mean 'works on Pi 5'.
Note my Pi 5 is not installed in the sbitx chassis nor does it have the sbitx software on it at this point in time so I can't test the sbitx with it right now.
