Over its history as an object in OSM it's had a whole variety of tags.  
Different people have said "This is important!  We should render it!" 
and have sometimes tried to do that by adjusting the tags until they 
found something that rendered.  Other people have tried to change tags 
to better reflect the current reality. 
http://osm.mapki.com/history/relation.php?id=6651797 tells the story.

Personally, I don't think that "boundary" would be a good relation type 
for it because it isn't one - it's the route of a former barrier within 
a boundary.  Compare 
with the suburb boundary just to the west.

Best Regards,
