Thanks for the details Mauro, are you aware of current or future uses of backports for media at this point? Adding media drivers was more of an experiment to see how hard or easy it would be to add a new unrelated subsystem, we carry it now and as collateral also carry some regulator drivers but its not clear the value in terms of users, so hence Hauke's question of removal of the regulator drivers. It'd be good to limit the drivers we carry to what folks actually use and care about.
