The main thing I envisioned for LinearRAID was to make it so that all
devices that can have a raid level always do. That makes it possible for
each device type to use the same calls to convert between disk space and
usable space regardless of whether raid is used (since it is optional
for lvm and btrfs). It also means that LVMLogicalVolumeDevice code to
convert between disk space and usable space will look the same as
MDRaidArrayDevice code that does the same thing.
