I am coming round to the view that it will never be possible to adequately
define what is considered a derivative work of OSM data.
The reason for this is that the possible uses of OSM data ore so varied that
one "definition" could not possibly cover them all.
As proof of this you only have to look at how long the "what is derived
work" question has been running on OSM. If we ourselves can not decide by
now what is a derived work, then no lawyer, judge, or potential user of OSM
data is going to be able to.

This above sounds nice in theory. What if one of the layers in fact
contained exactly the same sort of information that is held in OSM. However
lets say I was doing some mapping myself.
Rather than contribute "my" data to OSM I could have one layer with all OSM
derived data, and one layer of all my data. If additional layers were not
covered by the OSM license, then in this example all "my" data would not
have to be redistributed, and you may as well forget about the SA part of
the license.

Ultimately, I am reluctantly coming to the conclusion that either:
1) all OSM data should be released as public domain, and then we can all
forget about licensing;
or
2) have a license similar to CC-BY-SA, but allow specific exclusions where
the use of OSM data combined with "something else" does not lead to the
"something else" having to released under CC-BY-SA. These specific
exclusions would then either
i) have to be decided by the OSM Foundation on a case by case basis,
dependent upon who was using the data, what way it was being used, and what
it was being combined with; and / or
ii) examples of specific uses could be given by OSMF which would not require
the "something else" having to released under CC-BY-SA.
Neither option is ideal.
