Just to relay that message (not in my responsibility to make that decision):
This is very unlikely to change. btrs including qgroups provides some core
functionality which is marketed as part of SUSE Linux Enterprise and is
therefore seen to be enterprise-ready and *is* used by enterprise customers on
a big scale. Sure, many are also selecting a different filesystem. This is of
course possible and also fully supported. However, many users including myself
are running btrfs on a plethora of systems from server to micro-notebooks which
no problems which are *specific* to btrfs. I do have problems myself but they
are most likely related to the generic Linux behaviour in case of "thrashing",
