Give users a choice of file systems at volume creation

Problems related to the choice of BTRFS seems to be increasing, and I think many of us are just looking for a stable unit. I propose that users are given a choice of BTRFS or EXT4 at volume creation, together with a clear instruction that BTRFS is not good for all workloads but has more features. This way, users can be happy and NTGR have a fallback for support: "it seems like your usage pattern isn't good for the BTRFS file system, have you tried EXT4"?
