As a counterpoint to this, consider that street names in OSM include
directional prefix, base name, suffix, and directional suffix.  The post
office breaks down the standard components of delivery address line here:

https://pe.usps.com/text/pub28/28c2_012.htm

In this example of "101 W Main St S Apt 12" we would represent this address
OSM in the following tags on the POI Node or Area:
addr:housenumber=101
addr:street=West Main Street South
addr:unit=12

On the nearby Way for the street, there would be a "name=West Main Street
South" tag.

Values in addr:street do need to include numbered routes when the numbered
route is part of the actual address.  The post office shows some examples
of various variations on standard names for numbered routes here:

https://pe.usps.com/text/pub28/28apf.htm

To cite a specific example of how we might map something, consider the town
of Waldport, Oregon.

https://www.openstreetmap.org/#map=18/44.42718/-124.06667

As you can see, there is a US Route 101 running north-south through town.
Roads north of Northwest Hemlock Street include Northwest as part of their
names and roads south of Northwest Hemlock Street include Southwest as part
of their name.  US Route 101 is currently mapped in OSM with
"name=Northwest Highway 101" for the portions north of Northwest Hemlock
Street and "name="Southwest Highway 101" for the portions south of
Northwest Hemlock Street.  If we drop the name tag from this road in OSM,
then we lose the Northwest and Southwest directional prefix.  I think we
should retain the name tags on roads like this.

Here is an examples of a POI along this route:

https://www.grand-central-pizza.com/
Grand Central Pizza
245 SW Hwy 101
Waldport, OR 97394

USPS standard format of the address:
245 SW HIGHWAY 101
WALDPORT, OR 97394-3036

https://www.openstreetmap.org/way/463377211
addr:housenumber=245
addr:street=Southwest Highway 101
addr:city=Waldport
addr:state=OR
addr:postcode=97394

I believe this is correct in OSM.  The value in addr:street matches the
name tag on the nearby road.  The fact that the road is a member of the
route 101 route relation and ref=US 101 tag on the Way does not capture the
directional prefix on portions of the road.
