GrapheneOS always considers networks to be hostile and avoids placing trust in them. It leaves out various carrier apps included in the stock OS granting carriers varying levels of administrative access beyond standard carrier configuration. GrapheneOS also avoids trust in the cellular network in other ways including providing a secure network time update implementation rather than trusting the cellular network for this. Time is sensitive and can be used to bypass security checks depending on certificate / key expiry.

Changing this to the Standard (Google) mode will use the same URLs used by AOSP and the stock OS along with the vast majority of other devices, blending in with billions of other Android devices both with and without Play services:
A future device built to run GrapheneOS as the stock OS would be able to have a GrapheneOS attestation root and GrapheneOS attestation key provisioning service rather than a GrapheneOS proxy. A device built to run another OS without Google certification would need their own service and we'd need to support proxying to that service too.
Earlier generation devices we used to support prior to Pixels had Wi-Fi + Bluetooth implemented on a separate SoC. This was not properly contained by the stock OS and we put substantial work into addressing that problem. However, that work has been obsoleted now that Wi-Fi and Bluetooth are provided by the SoC on the officially supported devices.
Most apps that are able to run without Google Play services will have working notifications when they're in the foreground. Unfortunately, many apps don't implement a service to continue receiving events from their server in the background. On the stock OS, they rely on receiving events through Google servers via Firebase Cloud Messaging (FCM) in the background and sometimes even in the foreground, although it doesn't have good reliability/latency.
iPod Touch users originally had to pay for system software updates due to accounting rules that designated it not a "subscription device" like the iPhone or Apple TV,[178][179] causing many iPod Touch owners not to update.[180] In September 2009, a change in accounting rules won tentative approval, affecting Apple's earnings and stock price, and allowing iPod Touch updates to be delivered free of charge.[181][182]
A semi-tethered solution is one where the device is able to start up on its own, but it will no longer have a patched kernel, and therefore will not be able to run modified code. It will, however, still be usable for normal functions, just like stock iOS. To start with a patched kernel, the user must start the device with the help of the jailbreak tool. 2ff7e9595c
