If this is true, then it's a trivial enhancement to make that a configurable setting. 72 hours could be the default, if your security needs are higher, you could turn that down to 12 hours, or even less.

It could be hard-coded into the Secure Enclave so it can't be disabled if the phone is jailbroken.

A sufficiently powerful jailbreak would be able to override that.

Not aware of anyone being able to patch the Secure Enclave code to date.

there are public exploits to patch secure enclave code for some of the checkra1n devices. pongoOS uses the blackbird exploit on some models to remove a check that disables access to user data if the SEPOS boot code determines the phone has been DFU booted by checking the hardware TRNG state. https://github.com/checkra1n/PongoOS/blob/master/src/drivers...
