To an extent, yes, but I'm in this conversation to point out that we 
aren't going to achieve any kind of absolute consistency.

When a township names all its roads names like "Townline 131" and posts 
those names on street name signs, ref=TR 131 and addr:street=Townline 
131 become inadequate. [1]

When North Interstate Highway 35, a one-way frontage road, runs parallel 
200 feet away from northbound IH 35 but goes southbound, and the street 
name signs say "N IH 35", it should be tagged name=North Interstate 
Highway 35, not ref=I 35. [2]

When NE2 systematically removed systematic names from numbered roads in 
Ohio, he removed countless names that contained street quadrants. [3] 
You're right that these quadrants mostly matter in addressing, but 
there's a reason they often appear on street name signs. It seems 
inconsistent that a South Franklin Street would be tagged with its 
quadrant but that there would be no data, other than TIGER cruft, about 
whether it stays in that quadrant as it continues as State Route 122 
(South). [4]

I do like the idea of more specific name:* tags that indicate what the 
name can be used for, not just how long it is. As it is, a data consumer 
has to guess the degree to which a name=* can be used for wayfinding, 
addressing, or memorializing someone. It's only possible to do a 
mediocre job at best. [5]
