- Deleting checksum space would mean an immediate ODS change, right?
- Also, if someone wants to trade extra reliability for less performance,
checksum can be enabled. If you remove those bytes, that tweak can't be done
in the future. Make sure there's enough reasons to justify the gained space.
- What if someone wants the feature to track a ghost error that might come
from faulty hardware or SMP operation or garbage collection bug, etc?
