This "novel" feature is already supported by GrapheneOS and set to trigger after 18 hours by default, with the option for the user to adjust it to their preference. There is no good reason to force the choice of 72 hours on everybody. That's a user-hostile design decision.

This is an essential feature for my personal GrapheneOS phone. I only tend to use it once or twice a day most days, which means it is usually freshly rebooted every time I go to use it.

I remember reading somewhere that many new exploits in the mobile space only exist in memory and are thwarted by a simple reboot, including the infamous Pegasus spyware.

I am curious why you feel this is an "essential" feature. If you only use your phone once or twice a day, why would a hypothetical attacker bother targeting it?

If your phone contains sensitive information, perhaps pictures, financial information, texts, etc, and it gets stolen - this data could be extracted. But typically, when a phone is rebooted, the drive is encrypted. So you're good to go. Phone theft is quite common, and probably the thief won't bother trying to extract data, but they might.
