In my humble opinion: With intersected stations, I would say 'good'.
Even when being properly used these steeples etc were only being sighted TO, not from. In other words the OS surveyors never went up these spires.
I would say that if you have seen a given spire from a reasonably near point on the ground, say across the road, then 'good' should qualify. Mind you, I would also say that folk should not be logging things from a mile away, that hardly constitutes a 'visit'.
Hope this helps,
