Note that this is a substantially different task for 4.0 than for 3.0,
because 4.0 (particularly BY-SA) now includes a database copyleft clause.
Assessing how the ODBL and CC BY-SA 4.0 database clauses interact will be
challenging. OSM/Open Data Commons could simplify the problem by declaring
that CC 4.0 is a "compatible license" under ODBL 4.4(a)(iii), but there
would still be some complexities to work through.
