[OSM-talk] Proposed new status for tags in the wiki: "import" for undiscussed tags that were only used by an import

As Roland mentions tiger:cfcc tags, there is an argument (and documented wiki) that suggests they might still yield some underlying structure of the TIGER rail import in the USA which can provide useful data (in constructing route=railway relations, for example) still today, even as they have become somewhat smeared since their import.  It is virtually impossible to recognize all such subtitles of all such structured data that is now in OSM.  To say "this import seems to have 'grey' (old, misunderstood, seems to be 'noise in place') data, we should structurally treat it like x, y and z" REALLY must have some deep treatment about what these data were, are and might be before some wholesale data manipulation occurs.

Agreed on the iceberg! The world is a large place for view points and 
usage.


However the beginning mapper may have no knowledge of the tools 
available and count on the status as a primary indicator.

As such the status needs to distinguish those tags that are questionable 
for further use. And probably other flavors of 'status'.
