I ran a print recently that ran out of filament. FLUX paused the print, exactly as it should have, but I didn't go to check on it for a long time, and some hours later when I noticed it, the hotend was still on. For safety reasons, when there's a filament error, you might think about having the hotend turn off after a certain amount of time.
No damage was done, and I was even able to resume and save the print, but I consider myself lucky. If someone starts a long print and walks away, or something happens like the filament breaks or they forget or aren't able to come back for a while, there ought to be an inactivity timeout built into the pause function.
Just a tip. Thanks!
