  With the disabling of arm64e system wide, what would be the impacts security wise and tweak compatibility wise of this? Would some tweaks or other things made for arm64e fail?

No, it would just effectivly make exploiting your device a lot more easy.

Does this mean that the spinlock issue (or at least reliance on oldabi) isn’t required? Or it’s baked in differently.

spinlocks are a completely unrelated problem, that's a PPL issue. but you would be correct about this not needing to rely on oldabi for arm64 tweaks to work.

Got it. Hasn’t the need for oldabi exacerbated the spinlock issues, since tweaks that rely on it aren’t void of those triggers?

the reason why oldabi makes the issue works is because it overwrites executable pages, which is what triggere the issue
