And there is massgis:SITE_NAME, useful if it is different from name tag
(there are even 1729 ways with massgis:SITE_NAME, without name tag
indicating either really poorly done import or probably unwanted data
deletion - see http://overpass-turbo.eu/s/u3L )
Such useless tags are confusing and may mislead future users
that dumping random tags into OSM is a good idea. I think that data
would be improved by deleting such tags (except massgis:SITE_NAME that
is potentially useful).

It's actually a finished import from very long ago when norms were
This is an issue only in Massachusetts. I don't think you'll find them
in any other state (but if so please say where).
We locals are aware of this, and cleaning up the tags is on the
nice-to-do eventually list. But it doesn't seem that important or
urgent compared to other mapping needs.
