MTE performs fine on the Pixel 11 but it's only supported by Beta releases of the firmware.
The vast majority of low-level code in Android is still in memory unsafe languages. That includes nearly the entire Linux kernel which is the core of the OS security model. MTE in synchronous mode combined with other protections working alongside it is one of the few realistic ways to make Linux kernel exploitation much more difficult.
The massive amount of Linux kernel and Android memory corruption bugs is well known. The positive impact from good integration of MTE on this is very clear and compelling. These aren't unknowns as you're portraying them. Apple has understood the value of it and made great integration into iOS. The positive impact is very clear.
