It is to me. The problem with bcache is that it is a cache. ie if you
have a 256GB SSD and a 500GB HDD then you'll have total storage of 500GB.
Hot relocation was described as having 750GB available in the same scenario.
I'd also expect btrfs level support to be more friendly such as being able
to mount -o degraded if one of the devices is missing.
