Can eFuse Prevent Future iPhone Jailbreaking and Unlocking?

I've posted an interesting story a few days ago Motorola’s Droid X protects itself from hackers by self destructing
.
I admit the title of the article sounds more scary than it is in reality but it still makes me worry Apple might soon do the same thing as My Droid World describes:

The eFuse is coded with information that it either looks for or is passed to it from the bootloader. The bootloader is loaded with information it looks for when it begins the boot-up process. [...]

Once the the eFuse verifies that the information it is looking for or that has been passed through to it by the bootloader is correct then the boot process continues. [...]

If the eFuse failes to verify this information then the eFuse receives a command to “blow the fuse” or “trip the fuse”. This results in the booting process becoming corrupted and resulting in a permanent bricking of the Phone.

A hardware fix is needed to get the phone back on once the eFuse has been activated.

I wonder if Apple will implement this at some point in the future. We know Apple is against jailbreaking and unlocking so that might be a way to put an end to it all… at least until some smart hackers figure out a way to bypass this.
