If that can be done "off grid," then I welcome it because it's likely a jailbreak vector

Not a chance. iOS installs are cryptographically bound to the hardware itself installed on. It’s not possible to get an iPhone to boot an iOS install without an Apple server providing that cryptographic binding.

  Assuming it's implemented properly, that is. The whole reason Jailbreaks exist is due to bugs in Apple's implementations.

    Almost certainly not affected; even if this new recovery mode had no signature verification at all, you would have to deal with Apple’s impenetrable-since-A12 secure boot.

  Well, one will observe that I said "off grid," because I was acutely aware of the desire for them to approve OS reinstalls I know, "but muh sekurity" and all that, but when the grandkids find an antique iPhone 16 in a barn somewhere, and want to install an iOS image upon it to see how things were in the old-times, I want that to be technically possible even after Apple shuts down the old gatekeeping servers

    That's not possible because the requirement is built into the ROM. They'd have to release the keys and then you could emulate it.

Curious what you want from a jailbreak at this point? It seems all of the old things that were actually helpful have found them into first party software, or at least in the sanctioned third party. (internet tethering, emulators, side loaded apps, etc.)

  Internet tethering is actually one that's gone backwards, with "unlimited" cellphone plans that are limited when tethering. Or plans that disable tethering even though all the software is there. The other thing from a jailbreak would be for it to become self hosting, that is, give the ability to make full blown iPhone ipa on an iOS device without needing a macOS device anywhere at all.

    As someone who does a ton of networking/routing at the link layer for a day job, I can definitely see why they’re taking measures to reduce bandwidth hogs - to the extent I might actually prefer to be on a network that has taken measures to reduce hogging vs one that has not. When it really truly matters, like when I have a business need to download huge items in remote areas, the $10/GB+ justifies itself.

      Ironically, downloading huge items is easy to do without tethering. And video streaming, probably most people's biggest bandwidth use, fits very well on phones. Does anyone offer a tethering plan that's rate limited but not data limited?

And just like the original PSP’s batteries, you would be able to jailbreak an iPhone simply using a jailbroken iPhone.
