The transition to GDAL 3 was blocked by the removal of the Python 2 support as discussed in the transition bugreport (#939989). This took quite a bit of time to resolve due to an uncooperative maintainer, but there are no rdeps of python-gdal in unstable any more.
In the meantime the GDAL 3 support in fiona was fixed upstream. vtk7 was also updated to use the embedded copy of PROJ.4 to fix the FTBFS with PROJ 6. OSSIM upstream even ported it to use the GEOS C API to fix the build failure with GEOS 3.8.0. Unfortunately OTB still FTBFS due to recent changes in ITK4. It's still not in testing, so not a big issue. Hopefully we'll be able to start the transition soon, but I fear that the python3.8 transition is going to cause more delays (as it will cause many autopkgtest failure until everything is rebuilt for python3.8 as well).
