Android 17 QPR2 Beta 4 was released on August 28th. It's the first Beta release with Pixel 11 support. MTE support is still completely disabled in the OS and arm64.nomte is unconditionally passed by the firmware to the kernel. The good news is the firmware itself had MTE support added back to it.

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.
