[OSM-dev] How to handle these issues?

[Mateusz Konieczny]

ad 2)
- natural=land tag was used
- multipolygons were used to achieve the same goal
- multipolygons are better (solution of general problem), so natural=land
was described as bad idea
- existing natural=land gets replaced by multipolygons what is ongoing
process (see
http://taginfo.openstreetmap.org/tags/natural=land#map for progress - for
example in central Europe this tag is gone or was never used)
- JOSM since https://josm.openstreetmap.de/changeset/7391/josm encourages
users to update tagging (4 days ago)

Tag may be either used to use full available data or be ignored to make
data processing easier and encourage update of tagging.
