Well, I have only changed the tag on the bridges themselves, and only on
ways for which I did the original (and usually any subsequent) survey
and edits. So I am not corrupting other people's data.

Nevertheless, I agree that it is a problem with OSM-Carto, as I
indicated in the OP.

I have just been asked to give a talk about OSM to a local group
including Councillors who are impressed with OSM and considering 
using it for Council purposes. There are many historical abandoned
railways in the area (related to mining) and I think that they will be
singularly unimpressed if prominent major bridges on the local lanes
are missing. I suppose that it might be a useful lessson in
distinguishing the data base from the rendering, but there might be
sceptics present. Also I want to keep it simple at least for the first

So is there a bug tracker that I have missed for the stylesheet?
