OSM content sometimes shows up in Google at odd URLs rather than the standard openstreetmap.org domain, for example:


There is a `Host:` directive in robots.txt which should guard against this, but it appears that only Yandex supports it. Google's preferred solution appears to be `<link rel="canonical" ...>`. Probably only a nice-to-have and a workaround for a Google infelicity, but it could be good to support this.
