If you want to stick with a pixel maybe skip the Pixel 11 if you want to run GrapheneOS. There is some question whether P11 will actually support the MTE cpu extension which GOS requires for all devices it supports.

> ... There's a decent chance usable MTE will ship in Android 17 QPR2 and we'll be able to support it. We can't promise that since it's not up to us and no information has been provided about why MTE was unavailable at launch and still disabled in 17 QPR2 Beta 4.
