There is a lot of GIS data available for named points. 

Also, there is a lot of topography available as well, so someone manually mapping certian areas could create a pretty decent prominence value - from where they choose to measure. The issue a lot of people bring up is the "where you measure from" is relative to some other point - some people will assume different points are the "proper" point. 

In some places this won't be an issue, in other places - a big issue. 

Hopefully there is enough topographic information to programaticaly create values to check, rather than everyone choosing their own points.
