Actually i was using linux for years but had to switch to windows for research analysis software purpose. In that i used to have adb to remove google and other bloatware applications. Though its not permanent atleast they don't run either. Right In the windows too i have installed the adb. If so like you are saying that we can unlock bootloader without xiaomi then it really great thing. But i hope I don't brick my phone in the process, though its old phone i still use to avoid overuse of my current phone.
