While I appreciate this discussion, I don't feel this is the place for it.

Things like damaged/blocked roads, bridges, dams and even building 
damage data are verifiable on the ground. We work to train people in 
areas where OSM has little to no reach how to survey, confirm and care 
take the data.

OSM is about mapping what is important to people, and believe me, if the 
only bridge for 50km is out that is important to me and others.

I don't think we really tag this sort of damage very often, but when and 
where we do, we and others consider it important data.

So I would really like to get the most sensible tagging possible for 
damaged infrastructure and buildings and other disaster event related 
objects so where it makes sense to tag those in OSM we can tag them well.
