Major version changes such as from 6 to 7 often include database structure changes such as new tables or new columns in tables. These changes remain if you revert to a previous release; the database changes are not undone. The now-invalid changes might break calibre or plugins. Check library won't see these problems.

If and when you move forward again the changed entries will be wrong because they weren't maintained by the older version. calibre or plugins might not survive the experience.

Basically YMMV.
