It is possible but not in an automated manner.  With some very clever
automated heuristics it might be close to correct.  But certainly not
only by looking at the history of each object individually.  This is
one reason the current ODbL-status tools are of little value.

The second reason I see is that they look at CT-acceptance, which as
it stands is orthogonal to ODbL-compatibility.  Both of these things
are present in OSM now:
* data incompatible with ODbL but compatible with the current
licensing terms, allowed to be contributed under CT and
* data which available under ODbL (such as my contributions)
contributed by mappers who decline the current version of CT.
