[Tagging] Formally informal sidewalks

if you can cross everywhere, sidewalks are not separated but are part of 
the road (like a lane)
I tag : highway=residential + sidewalk=both without any separated 
sidewalk path
I think that your sidewalk must be review :
keep isolated sidewalk as there are right now.
but merge sidewalk with the road where the is no space/barier between them.

For wheelchairs routing, I put kerb=raised on the highway and a 
highway=crossing crossing=unmarked kerb=lowered where wheelchairs can cross.
