Fairly certain it's just another person wanting to go the extra mile of security. Sure, it may not do anything useful if you're just some guy Pegasus won't ever encounter. But if lockdown mode doesn't restrict OP in any way, what's the drawback of just enabling it to sleep that little bit better at night?
Seems most likely, but there’s nothing I need to say in that scenario. May as well cover the long-odds case in the off chance that I save someone’s life.
