Many, many sidewalks do not have any rebar in them at all and they hold up just fine. Typically, the rebar is there just to reduce the cracking in a slab on grade situation; unless the intended use will put a lot of weight on it.

Does concrete have to have rebar?
Not all surfaces need concrete rebar reinforcement, but adding it makes concrete stronger and more resistant to large cracks.
