Arguably it is a different layer, but it is still a license restriction 
based on intellectual property claims.

Several open content projects only accept content released under certain 
well-known licenses and do not allow additional restrictions on the 
license. OpenStreetMap would have to go to all those projects (including 
Wikimedia Commons, the various language editions of Wikipedia, and a lot 
of projects that we may not even know about) and find out if they agree 
with your interpretation.

 From a practical point of view it would be much better to proactively 
make sure that maps from OSM data can by CC-BY-SA, GPL etc. licensed 
without any additional restrictions.
