Do you know if that's the process for the 2026 Signature? I don't remember exactly but GrapheneOS may have mentioned that for the current Motorola flagship devices the unlocking isn't as onerous.

Considering Motorola is doing a lot of the porting, I would guess it will be improved or will be easy.

If there's a "process" that isn't just something done on-device, it is vulnerable to a rug pull (see LG, Sony, Nokia) where they just suddently stop offering it or the service just stops working somehow.
