I think the imposm-way with having tables grouped by tags (a "amenity" 
table, a "highway=roadway" and a "oll other highways" table) will be the 
better approach when it comes to rendering.

This is different then what is needed for a history api - here we need 
the classic schema with nodes, ways, relations.

My personal, next goal is to get a WMS up that allows displaying the map 
at arbitrary dates, so I'll go the imposm-route.
