We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.
That doesn’t make sense when you stack it against the cost of other efforts Google takes with the pixel phones surrounding security. MTE is arguably more important than even the titan chip, and a whole security enclave isn’t exactly cheap either.
