And if these signs are placed by the highway authority? I think these 
most definitely do have a place in OSM. It's then up to the data 
consumers whether they attach any value to them. By making the data 
available, we are enabling  e.g. HGV routing programs to take these 
hints into account. Without these hints, trucks may be directed down 
"unsuitable" routes. The political process leading to their erection is 
not important - only their existence. Political pressure has a large 
influence on speed limits as well.
