That would be interesting. I have long wished that Sony phones would allow re-locking the bootloader to an OS signed with my own keys.
Some of their Xperia Compact models have been excellent, but they haven't been making them like that in recent years. Dare I hope for a return of their truly compact flagship phones and GrapheneOS support?
As far as I'm aware, their flagship Xperia phones do support bootloader re-locking [1]. The problem is they haven't fulfilled GrapheneOS's other requirements: https://grapheneos.org/faq#future-devices
