To calibrate your sense of time, the iPhone 15 had been released in September 2023 and that doc is dated April 2024, so ~6 months.
And just for completeness, here was the Android doc that leaked at the same time: https://www.documentcloud.org/documents/24833831-cellebrite-...
I'll be amused when Apple finally drops a portless iPhone as the next step ahead.
(Apple already has their Qi2/Magsafe setup, and they already have been using 60GHz wireless USB for quite some time now internally with the Apple Watch for diagnostics and service management since Series 7.)
I don't know, even the latest and greatest is eventually cracked, or they can just hold your device in evidence until the capability is there a few weeks (or months) later.
Furthermore by using an official OS from a vendor like Apple (or Google, Samsung) there's always the possibility that they could target your device with a specially crafted update, especially if you're in really big trouble.
