Providing you can keep it from spreading over the actual slabs, I'd be inclined to leave it. The contrast between the grey and the green looks rather attractive IMO
I have the same problem but because my slabs are in a small, narrow area and drop down in 3 stages, there is never sufficient air and sun to keep the moss from establishing ( and re establishing after cleaning ) over the actual paving.
Just trying to keep it in check, last year I cleaned and re mortared the cracks......big mistake as the flood water last winter had no where other to go than into my kitchen
