Has consideration been given in any future API/database schema updates 
of having support for layers, like e.g. the GIMP does it for graphics? 
So you could import data into a new layer with all the appropriate tags 
and then "merge down" as appropriate. The slippy map would only show the 
base layer. This sort of support might also be useful for people reusing 
OSM software and schemas who want to overlay their own data onto the OSM 
data.
