The temporary nature of Google eSIM management on GrapheneOS poses a critical issue when one forgets the eSIM PIN and attempts to disable the eSIM using the PUK code screen. If the eSIM is locked due to failed PIN attempts, the phone becomes completely unusable. Disabling the eSIM is impossible due to the lack of Google eSIM management privileges. Moreover, the phone appears to lack the ability to handle any eSIM-related actions, further compounding the issue. Consequently, the phone becomes unusable even after multiple failed PUK attempts (in my case, 10). Without the ability to disable the eSIM, the phone remains unusable until a factory reset is performed. The worse case would be that the system can't disable the eSIM after failing the PUK to many times, resulting in the previous mentioned problems.
