Not that I am aware of.
RichardF's proposed solution was to put a time limit into the
contributor agreement (change of license only possible at or before date
X). My gut feeling is that not much is won by that; either the date lies
too far in the future to have any effect on people's decision now, or
the date is so close that it is unlikely for us to encounter major
license stepping stones before that date so it's not worth the hassle.
Another solution could be to introduce a special class of accounts which
have not signed the contributor agreement. Data contributed by those
accounts would be part of OSM data just like anything else, but would be
at risk of being removed in a possible future license change. Accounts
of this class would have to be requested individually from OSMF, and
would have to carry a detailed explanation about the provenance of the
data, and why it may not be relicensed at will (and whom to contact
should there be a concrete demand for relicensing).
This would retain the flexibility the LWG was looking for while at the
same time opening a back door for anything that is not compatible with
the contributor agreement. While still creating the risk of data loss at
a future license change, that risk would at least be clearly docmented
and it would be clear which data is potentially affected.
