Incomplete isn't the problem -- the metadata.opf files are themselves merely a backup of the DB. However, the metadata backup exists to make your library useful in case the DB gets FUBARed, which means one would be well advised to keep them.

Assuming the backup contains an entirely working DB, which is not something I personally want to be dependent on, calibre will simply regenerate every one of those metadata.db files -- so if his backup didn't take time copying them, calibre will take even more time making them.
Why does he even care -- they are both background non-intrusive processes???


Either way, backing up the DB and not the OPFs is at least potentially dangerous, for, practically speaking, no net gain.



My backups are meant to protect against two points of failure -- database corruption, and library corruption.
I do not see how it hurts to protect against both happening at the same time. It is not significantly more unlikely than the possibility that one alone would happen.
