The mess that CFQ is certainly not. But we want to eventually be able to get rid of the legacy request code, so we need suitable I/O scheduling. See the threads at: https://lkml.org/lkml/2015/11/19/227 or http://thread.gmane.org/gmane.linux.scsi/111257/focus=111320 for more details. A leightweight bfq-like scheduler might come in handy on top of Andreas' time slicing work.
