The list of auto-approved items seems somewhat arbitrary, but I think they had privacy concerns in mind when they made the list (although it seems stupid that you can't override those protections if you'd like).

All of the ones on the "cannot be run automatically" list are things that a bad actor could do if they had your phone, like wait for a certain time of day, or move your phone to a specific location, or bring it in range of a particular bluetooth or wifi device.

But then, NFC is on the "can be run automatically" list, meaning that a bad actor could touch your phone to a NFC tag to trigger an action, so that doesn't make much sense. The rest of the items on the "can be run automatically" list are all ones that require your phone to be unlocked (I think).

Very odd choice by Apple for something that will be used by relatively few people and would greatly increase the usability of the feature
