FWIW, there's a path to downgrade PS4 to the previous firmware, see https://wololo.net/2022/12/06/it-is-apparently-possible-to-r...

This also helps for when an exploit is found, like say the issue with Firmware 4.51 and lower.
It's super easy to fix then - cook up a new DRM and encryption scheme (or modify the current one) that, without access to the internals, is impossible to figure out. Doesn't take much - probably just a generic encryption key that gets swapped out. Then, roll that out in an OS update. Finally, make new games use that encryption scheme and thus that firmware level.
Sure, games that run on 4.51 or lower are cracked. New ones? Uncrackable, until a new jailbreak is found.

The PS4 scene is full of downgrade patches. Many games targeting 10.x for example didnt make use of newer syscalls and it was discovered how to patch the game for 9.0 (the 9.0 firmware has a jailbreak).
It's also notable that these firmware exploits never drop out of the blue anymore either, since the console manufacturers started doing bug bounty programs (up to $50k in Sony's case) they always get advance warning when someone does find an exploit and it's fixed before anyone knows about it, by which point most people have already updated to a fixed firmware and it's too late for them to jailbreak.
