It supported clamshell and open, and has for as long as I remember.
But the toggle between the modes had been this slow experience that seemed similar in delay to switching resolutions.
Now it is this blip—-this is your main display, and you can toggle it if you rapidly open and close it, which I can’t really recommend except to cement in your mind that this is the new normal.
I own M1 MBP16. While closed laptop technically works... One nasty bug makes it unusable. I can't reliably switch keyboard layouts using globe button. This bug is absolutely weird and ridiculous and I have no idea how it's even possible. When laptop is opened, I press globe button and my keyboard layout is switched. Actually it does not work 100% reliably, but it's OK. With laptop closed it works like 20% of time.
Have no idea about ventura, will not update before first patch, I guess.
Did this _not_ work on the same M2 laptop while on Monterey?
(I've had this on Monterey from the beginning on M1 MacBook Pro)
