Obviously, it depends on the router.  In some cases I suspect "it 
isn't"*.  The instance of OSRM that is linked to from osm.org doesn't 
like foot routing on trunk roads - see 
https://www.openstreetmap.org/directions?engine=fossgis_osrm_foot&route=54.0440%2C-0.9416%3B54.0410%2C-0.9469#map=14/54.0414/-0.9253 
.  That router is hosted in Germany, where as I understand it things 
tend to only get tagged as "trunk" when they are also "motorroad=yes", 
so perhaps it's applying "normal German tag usage" worldwide.

In this example, the relevant bit of trunk road 
https://www.openstreetmap.org/way/868354780#map=16/54.0434/-0.9456 has a 
sidewalk tag on it, and I'd always suggest ensuring that things like 
sidewalks, verges or shoulders are mapped.  There will still (as here) 
be data consumers that ignore that information, but hopefully in the 
future those issues can be resolved.

Best Regards,

Andy

* There are exceptions - from memory I think that https://cycle.travel 
is one example that does have different rules in different places
