IMO, no. It's particularly difficult when such a user joins the landuse 
ways to the road ways, presenting all sorts of opportunities for newbies to 
do "the wrong thing" when editing anything in the area. Even attentive 
editors have to go through all sorts of difficulties when dealing with 
splitting ways for turn restrictions, etc.

I map landuse out to what is likely to be the part of the land that the 
owner can actually build (or landscape) upon - generally the inner (i.e. 
away from the street) border of the sidewalk. Also, I rarely map individual 
parcels, choosing instead of map the outline of an entire tract. In this 
case, the landuse _will_ cover the roads that are interior to the tract or 
provide access to it. See
