Well, that's up to the devs to decide. Also, it is not about the "flagship". POCO is a standalone company which focus on software development - the reason why it takes the user feedback more seriously and pushing out faster updates. The ROM community in XDA is also far better and active due to the fact that POCO supports bootloader unlocking (will NOT void warranty) and Android development in general. Pocophone F1 is a budget flagship only, but its strength is the developer community in Mi and in XDA.
