Looking at the code, if priority languages are set, we store the reason even if it is empty. Similarly, we store priority force (as off) even if the option is selected
The code can be updated to avoid saving rows if:
- If reason is an empty string (363 rows on MetaWiki, 46 in MediaWiki.org)
- If priority force is 'off' (413 rows on MetaWiki, 43 in MediaWiki.org)
After the code changes are deployed, we need to run a script to remove these existing values.
