I've had my Framework (w/Arch and KDE) since 2022 and have yet to have any problems with sleep. I can safely unplug from my monitor/dock, close the lid, and drop it in my bag. It's never tried to cook itself while in sleep.
Battery life in sleep (and in general) could be better, but on the whole I've been quite happy with it.
