That would be a pity because it limits our freedom to personalize and tweak our devices. Pretty confident there will always be a workaround that but will read more about it. Thanks

You can relock later with the mi flash tool. Flash original rom a has a relock option. Personally I think those warnings are only to scare you...

Ok, the only other suggestion I have is to flash first the fastboot version. It's the 11.0.7. after flashing that version on fastboot you can dirty flash through twrp the 11.0.9.
