i would agree with you. not being familiar with internals in this case, 
i don't know how
hard that would be to adjust. however, at a minimum, there probably 
ought to be some
sort of documentation/help option available for errors and warnings so a 
newish user
can get immediate feedback on whether a fix is advisable,  maybe right 
click/help-with-error
leading to a text help dialog?

and from a practical point of view, this is how they are in the database 
at the present time; nodes
for landuse/areas are at the same locations as nodes in highways.
