Particularly when it s been announced there is a Jailbreak for PS5 sure for V4.03 but that s the first foray and there could be one for a live version at one time.
PS4 also should have sooner rather than later another route.
One shouldn t think they will be free of annoyances on playstation (but i would think the worst to happen there would be the botched save and game crashing), particularly if a doctored save is enough to do it.
With a little luck, it can be fixed with their network solution server side (which has some updates from time to time) , rather than the actual games (i wouldn t be surprised if they couldn t do a build of the old ones because of all the deprecated libraries and out of date development tools).
ER being opt in networking there is way to setup password only network play. Since it s in active development, if they can't fixed the server side, the client will be fixed for sure.
