- On step 11 you can choose to allow (or disallow) removing the profile with a password
- Alternatively you can backup the pairing records from your laptop somewhere to be able to put them on a new laptop

Yes, although if the premise is that you're being compelled to unlock your device by law enforcement then it seems like they could also compel you to disable Lockdown Mode and restart your device - that's not possible with Pair Locking.
iPhone users are pretty safe even without supervision and the special profile, right? Don't they have to authenticate (passcode) to allow a forensics tool to connect? Still, I appreciate the idea to put up another barrier.
