That's quite easy:
Where there are no crossings - no crossings can be used, any routing 
will use the nearest point approach - with 'wild crossing' ("your 
destination is on the other side of the road") or "use the road" - the 
rest is your personal responsibility to adhere the laws and to preserve 
your health.
Where there are no sidewalks - well, there are no sidewalks, you and the 
router will have to use the 'road'.

A router that does consider sidewalks, will _prefer_ sidewalks and use 
roads otherwise.
A router that does not consider sidewalks will use the roads anyway.
