If you care about jailbreaking, I strongly recommend against updating to iOS 27.2 when it drops, as 27.2 Beta 3 is rumored to have patched an SPTM bypass. Feel free to spread the word on this. While this doesn't have anything to do with what Calif showed off, it could still be used for a jailbreak on it's own (of course support for >26.0.1 requires a new kernel exploit).
