[OSM-dev] CC-BY-SA datasources, display warning in editor?

there are a number of data sources which have agreed to being used
for CC-BY-SA licensed work but where it is not yet clear if data derived
from them can be carried over once we change to ODbL.
I'm thinking for example of Nearmap aerial imagery.
It is possible that data being traced from these sources will have to be
removed later, even if the user doing the tracing agrees to ODbL.
In fact, users who have newly signed up *already* have agreed to having
OSMF release their data under ODbL, so their tracing such imagery might
actually land them in a spot that Nearmap lawyers consider illegal.
I think it would be good if editor writers could make an effort to
inform users about this potential problem, effectively telling them to
postpone further use of that data source until the licensing questions
have been sorted out. Otherwise people might just put in a lot of work
