If you methodically use a geocoder to reverse engineer the OpenStreetMap
database, share alike would kick in. "Reverse engineering OpenStreetMap"
would need a better definition and it would have to cover two dimensions:

1. Comprehensiveness (not just a "narrow extract" like addresses, buildings
or businesses, but rather a comprehensive extract of the most important
OpenStreetMap features together)
2. Geographic size (e. g. a country)

We could establish these limits with an update to the community guidelines
for what's Substantial.
