Well, if you produce Geospatial PDF or georeference the bitmap, you will
certainly allow people to locate the features of your map "in the real
world". But isn't that the whole purpose of a map? And Web tiles are by
their nature georeferenced. And if you generate a vector map of your part
of the town, that would mean high-enough resolution for someone to trace
the features over it.

I like the "intent" idea: on one hand, you could produce a vector map as a
visual instrument of conveying information and that should be OK. On the
other hand, someone could produce a SVG that would contain additional
"ghost" XML information about the original OSM database elements (IDs,
tags, exact coordinates) - that would really constitute a replication of a
database and that should not be treated as a Produced Work.
