Reverse Engineering iOS 18 Inactivity Reboot

Two questions:

1. surely unconditionally rebooting locked iPhones every 3 days would cause issues in certain legit use cases?

2. If I read the article correctly, it reboots to re-enter "Before First Unlock" state for security. Why can't it just go into this state without rebooting?

Bonus question: my Android phone would ask for my passcode (can't unlock with fingerprint or face) if it thinks it might be left unattended (a few hours without moving etc.), just like after rebooting. Is it different from "Before First Unlock" state? (I understand Android's "Before First Unlock" state could be fundamentally different from iPhone's to begin with).

What legit use case involves not touching your phone at all for 3 days?

Not a phone, but at my old apartment I used to have an iPad mounted on the wall. It was a dynamic weather display, Ring doorbell answerer, multimedia control, etc. Would suck if every 3 days I had to enter my passcode again.
