I endorse this opinion. The BBL should never have been merged as-is. Without a block reallocation system like a real hard drive, a BBL entry simple drops redundancy on the block in question without any other corrective action. Completely, utterly, brain-dead. At the very least, it should not be enabled by default on new arrays.
