It's possible to enable reserving the tag memory for MTE via `fastboot oem mte on`, boot a non-stock kernel ignoring arm64.nomte and use MTE. We're in the process of determining whether it's fully functional and the performance characteristics. It's likely disabled due to performance being ruined.

We expect performance must be quite bad for Google to have decided to entirely strip out support for it in not only the software but also the firmware so that no would could even try to use it before Android 17 QPR2 Beta 4. That's a very strange thing to do. It's at least added back to firmware now.
