Well, the risk there is slightly higher as you are assuming rescue partition does not have an exploit planted? Empirically, we've had iOS jailbreaks that exploited higher level kernel, but not bootrom. That said I do it because DFU has been just faster than having the system do "Internet Recovery" not strictly for security purposes. FWIW, you do not need another Mac to DFU restore another. Any computer could do[1]. [1]: https://github.com/libimobiledevice/idevicerestore

This may work for you for restoring using Linux, but you'll want good backups: https://github.com/libimobiledevice/idevicerestore

Just use https://github.com/libimobiledevice/idevicerestore on a Linux or Windows machine. Yes, if you don't have internet access you have a problem, but I'm personally happy enough with the benefits of this security model that I'm willing to accept the tradeoff.

I don't know about Windows, but it runs on Linux, yes, and it works on at least the M1 Mac Mini. See: https://github.com/libimobiledevice/idevicerestore/pull/406 There's some bug with the laptops, but it should be easy to fix once someone takes a good look at it. I might spend some time on that; I definitely want idevicerestore to be in good shape before we start encouraging more wide usage of Asahi.
