Maybe I've got the wrong end of the stick but my impression is that it 
is the use of "the_repository" in library code (i.e. the files outside 
builtin/) that causes most of the pain. With that in mind would be we 
better focusing contributor and reviewer effort on eliminating 
"the_repository" from those files instead? It would need to be done in 
carefully in stages but would bring real benefits.
