Since LPM support is based on the iPhone’s hardware, it cannot be removed with system updates. Thus, it has a long-lasting effect on the overall iOS security model. I remember in the 00's there was a bunch of action films which prominently showed people taking out their phone batteries in fear of the authorities, it was portrayed as ultra-paranoid at the time but turned out to be correct in hindsight. Only a few years later removable batteries became obsolete. I think the Samsung S5 was the last flagship Android phone to allow it.
