OK, imagine the following;
Suppose that some time from now, OSM has moved to ODBL - and a group has
forked OSM using the last CC-BY-SA planet file - for the sake of argument
call it OSM-CC.
The original OSM project, with the database under ODBL still releases its
map tiles on its main website under CC-BY-SA.
Presumably, the OSM-CC project would be well within their rights to use the
OSM created map tiles as a background layer in JOSM / Potlatch etc. to allow
users to trace map data. The data created is derived from the CC-BY-SA
tiles - and so must therefore also be under a CC-BY-SA licence. Therefore
it's compatible with the OSM-CC project.
With sufficient resources, the OSM-CC project could in theory create a
substantially similar database to that of the main OSM project - although
it's extremely unlikely to be identical.
