Love it. Locking my parts to my device when activation lock is on will be great at making my phone less appealing for thieves.

I don’t see a downside here aside from shops being unable to buy stolen components (cry me a river) to undercut legit repairs. Yes there will be fewer components available because some phones will be unable to be unlocked when damaged so the parts can’t be scavenged. Pity shrug.

I’m ok with shops being able to repair devices with 3rd party components however the device should show a very visible alert message when starting up (rather than being buried in a menu somewhere). “This device contains non-original components” so people aren’t mislead if buying a used device.
