It is not me :-)
But as talk a few weeks on talk mailing list, create a separate walkway 
when in fact it is actually connected to the road breaks the routing.
A routing suggests that you can always cross the road when in reality it 
is not always true (barrier, hedge, ...).
Another assumes that you can never cross if there is no path between the 
barrier and the road.
For now, IMHO the best solution is to add the tag sidewalk to the road 
when the counter is against the road. The kerb tag is then useful for 
people with reduced mobility. The geographic precision is less but in 
any case the gps regularly have an imprecision as great as the width of 
the road.
There is a proposal to improve routing for separate trotters but it is 
not completed and no routing to my knowledge uses it

PS: Look for the example described on talk, you will see funny results.
