Only 17 listed buildings along it...
Living two minutes from the street, and cycling it often, the surface is currently abysmal, but I'd be all for the retention of setts.
EDIT: 15 (didn't notice the last two were down south). For a short street that's quite a lot of listing, mainly good examples of Georgian architecture, with the church being stunning/ugly, depending on the view of buildings that look like Thunderbird 1. All in all my point simply being it can't be claimed at all that the street is architecturally unimportant!
