> The very specific RAID configuration is a non-issue for 99.9 percent of people

"Very specific" being the most common RAID configuration used outside of personal computing (when you have more than 2-3 disks, you aren't running RAID1/RAID0/RAID10, it's all RAID 5/6). And funnily, one of the main scenarios where an advanced filesystem is actually genuinely needed and not just a nice to have, is when you have lots of disks.
