Can this btrfsmaintenance just be removed by default? It seem to cause more troubles than good. Besides, balancing of btrfs nowadays is not recommended, according to btrfs kernel wiki. And balancing with -susage=... is plain dangerous. Modern btrfs tools wont even allow to do it anymore unless you force it. And scrap won't help if you don't have redundant copy in some sort of raid. So this package basically does a lot of troubles all around the system without any real benefit.
