We do. A24, for instance, is still making a couple movies by agreeing to work under the proposed terms by SAG. As far as I know, no one else has made such agreements yet. The more of such exceptions that get made, the weaker the AMPTP’s position will get.
Imo that’s still not enough. Plenty of crashes or failures happen in a way where loading screen animations still keep playing. Having a cursor you can move around to validate that the process is still responsive is important feedback.
I also remember lots of games that did exactly what you are saying and there was no way to tell if it had hung during loading or not because you couldn’t check if it was accepting feedback.
IMO it’s a good feature and it’s a good thing it’s required. I remember the days when I would boot up a game and never be sure if my system crashed or not.
This requires the game to start giving you feedback before you start wondering if you should do a power cycle.
