Which is a very powerful feature for anyone who likes security or finding bugs in their code. Or other people's code. Even if you didn't really want to find them.
It certainly took them a while to introduce MTE! Pixel 8 came out in 2023. I wonder how it compares against hardened_malloc with 48-bit address space and 33-bit ASLR in Graphene. Apple's security team has reported that MIE could break all "known" exploit chains, but so does hardened_malloc. Hard to tell right now which one is best (most def MIE) but everything else included in Graphene is probably making the point moot anyway.
