Would it be possible to add a CC BY-4.0 (or other equivalent) licence alongside ODbL for the Microsoft Building Footprints dataset? [Google’s Open Buildings project](https://sites.research.google/open-buildings/) is licensed under both ODbL and Creative Commons Attribution (CC BY-4.0) to avoid licensing issues. Adding CC BY-4.0 to Microsoft Building Footprints would make it much easier for us (and many others) to use the data while keeping it open.
