If "extending Activation Lock to other components" means what I think it does, then the phone's owner should have control over this and 3rd party repairs should be fine. It may cut out the market for unofficial parts, but does that even exist today? Is anyone making iphone compatible batteries with any scale? (I'm curious if so)

The thrust of this move devalues phones to thieves, which I generally think is a good thing. Cutting down the hardly salvageable value even further should help the "market" sort this out and lead to less theft. I like it.

Third party parts exist for tons of Apple devices. Usually of varying (typically poor, especially with batteries) quality. You can get OLED screens (actually oled!) that are replacements even. They pretty much will all give you the “unable to validate authentic component” message when paired with an iPhone … but that’s kind of working as intended there.
