To be paranoid, we limited chunk merging to empty chunks, and only two-at-a-time. We should probably revisit this once merging chunks have had some burn-in time to provide inverse functionality to split chunk (merge multiple).
In particular it's awkward and racy to try and validate that one of the merged chunks has no data.
