Lockdown mode in Android 15 protects your phone from 'juice jacking'

When lockdown mode is enabled in Android 15, USB data access will be disabled, preventing potential "juice jacking" attacks.

Points taken from article:

Android 15 is adding a built-in mechanism to protect your device from “juice jacking” attacks.
Charging will be allowed when lockdown mode is enabled in Android 15, but USB data access will not.
Juice jacking is a largely theoretical problem you don’t really need to worry about, but it’s still nice that Android will protect you against it.

This can also be practical in places where the police can force you to unlock your phone with biometrics but not with the PIN.
Ever since I've seen the police here force people to delete the videos of them abusing citizens, I have been very wary of biometric identification.
So far my 'emergency' procedure would be to restart my phone, as it's asking for a PIN after a reboot.

LineageOS has been doing this for a year or so already.
- Same on GrapheneOS :)
- It’s smart! Do not expose logic without first supposing an appropriate level of trust. Software can have errors.
- Pixel UI seems to have it too, but does that not prevent data transfer?

How is this different from current Android
- Lockdown mode was introduced in 2018’s Android 9 Pie release as an optional feature users could add to their power menu. When enabled, lockdown mode hides notifications and disables all forms of authentication except for the user’s primary authentication (PIN, password, or pattern). In Android 12, Google made the lockdown mode toggle appear by default in the Android power menu, though some OEMs hide it or offer their own, similar version of the feature elsewhere.
  Android 15 will further restrict USB access in this mode to help defend against attacks.
  
  Don't you already need to unlock the phone to change USB protocol?
