Okay, if it's that serious than apple should simply turn it on for everyone. Having toggles for Lockdown mode adds complexity and risk.

The number of users who currently know they need to toggle on lockdown, and would be confused by having toggles under it like "Disable JIT, Disable link previews", etc, is approximately 0.

The number of users who would turn on "disable link previews" and be more secure, but won't enable all of lockdown, is at least me, so that's more than 0. By that logic, it follows that splitting it out makes more users more secure, right?

Let me know where I'm wrong there. Do you legitimately think that there's risk of users knowing they need lockdown mode being unable to find it if there's additional settings added? I guess apple can't add any new settings anywhere.

Do you think that more settings means apple is more likely to introduce a bug that impacts security? I guess apple shouldn't be allowed to add any new settings anywhere.

Perhaps it's time to acknowledge you probably don't know what another persons situation is. Instead of trying to tell them what to do, allow them to choose.
