There are almost no motorway_link roads in the United States with a posted speed limit at all. And if a speed is posted, it is nearly always an advisory value rather than a mandatory limit. How should one tag what one sees on the ground for that?
For what it is worth, the only router I’ve seen that has an issue is OSMand. And the fix is easy (I’ve done it in my routing.xml). Just because the developers of one routing engine need help is no reason to make up fake data to keep it happy.
