I noticed that the wiki describes City, Town, Village and Locality to be named based on a determined size.

Example: Use place=town to identify an important urban centre that is larger than a place=village, smaller than a place=city, and not a place=suburb. Towns normally have a good range of shops and facilities which are used by people from nearby villages.

My suggestion is that includes the local legal/administrative size denomination. Many countries have a legal/administrative approved size for naming for City, Town, Village, Locality.
