By asking the copyright owner to give OSM the right to re-license their data as OSM sees fit, you're effectively asking them to release it into the public domain. By itself, this is a huge ask. "Explicit authorization" isn't a license, and there must be a written license, so we must be specific here. There is a huge amount of ODbL-only licensed data in OSM already. To name just a few instances, the massive AND Netherlands import [1], plus everything derived from the UK's Ordnance Survey OpenData [2], much of which is raster data which has been traced individually by users and would likely be impossible to effectively remove from the OSM database. Working out derived works in a GIS seems to be a legal minefield in itself - if you use ways which are imported from an ODbL-only source to help align your own mapping, are you creating a derived work? My impression is that any opportunity for a relicensing event as alluded to by the Contributor Terms has long since passed. A significant part of the OSM database is either covered by ODbL-only licenses or may be considered to be derived from ODbL-only sources. I'm not sure if this even matters, though. The License FAQ [3] does express reservations about importing data which could be removed by a future license change. But we're talking about *building heights* here - it would be simple to clearly identify the source of this data, and it's highly unlikely that there would be any derived works created from building heights. It's probably one of the most independent pieces of data you could possibly import into OSM. This discussion just seems like unnecessary pedantry here, and I think if clarification is sought on these (rather technical) legal aspects, the correct place to do so would be on the legal mailing list.
