LFS3_CKDATACKSUMREADS is just too much. The downside is it may not be clear how LFS3_CKDATACKSUMREADS interacts with the future planned LFS3_CKREADS (LFS3_CKREADS implies LFS3_CKDATACKSUMS + LFS3_CKMETAREDUND), but on the flip side you may actually be able to type LFS3_CKDATACKSUMS on the first try.
