I've made a practice of removing all tiger:* tags, and most gnis:*
tags (except feature_id) after verifying a feature. The only external
data that I think belongs in OSM is a reference number (i.e. primary
key, e.g. gnis:feature_id) that can be easily maintained (e.g. no
tiger:tlid), and that should end if/when we have persistent IDs. And I
think we shouldn't use a private namespace but put it under the ref:*
namespace, which makes clear the purpose of the data.
