Currrent state
There is no generic persistent key-value store in MediaWiki. This results in creation of multiple tables even when underlying data doesn't need joins with other tables or lookups by various fields.

Examples of such tables that are never going to have more than 1 row:
 * site_stats (core)
 * geo_updates (Extension:GeoData)
