For wheelchair routing.
If all crossing have a lower kerb, it is maybe enough to add 
sidewalk:both:wheelchair=yes to the street.
But if some crossing have a raised kerb, wheelchair routing can't work 
without a crossing with any existing way including service.

I have the opposite :-)
Maybe connect the entrance of the house with a path to driveway.
Maybe map only the beginning of the driveway where the crossing is located.

See the first question, create a sidewalk path separately in osm from 
the street where the sidewalk is in fact hooked to the street create 
currently more routing problem that it solve.

you can add those tag to the street as documented here
https://wiki.openstreetmap.org/wiki/Wheelchair_routing#Sidewalks
for example I use the following tag on the street :
kerb=raised
sidewalk=right
sidewalk:right:smoothness=excellent
sidewalk:right:surface=asphalt
sidewalk:right:tactile_paving=no
sidewalk:right:wheelchair=yes
