I wonder why are there not a lot of custom ROMs for Sony Xperia phones on XDA Developers forums?
Looks like Sony provides the bootloader unlock codes and sources required to build AOSP for their devices 🤷

Specs of this to be released phone look amazing and it still has a headphone jack and SD card slot, but using stock ROM with all that Google bullshit sounds scary.
