Just after sending, I thought of another variation: Report the number of *invalid* pages (which we already track) as checksum errors, if there was at least on checksum error. It's imo rather weird that we track checksum errors but we don't track invalid page headers, despite the latter being an even worse indication of something having gone wrong...
