Review Comment:
This seems a bit dangerous to me. I get we're saying it's required, so we
don't need the null value but I looked around to see where
manifestFile.snapshotId() == null checks are performed, and there's quite a
few. For example `RewriteDataFiles`, `AppendFiles`. This may break some of the
existing logic there by exercising the other branch in the code?
