   Indeed snowflake is now bumped and I believe it is not a blocker any more. 
   
   I built the image recently and unfortunately I think we have another dependency problem - pyarrow/numpy which we are using in a version that has no binary packages built for python 3.9. Possibly that can be fixed by building the older versions of those libraries, but I think ultimately it means that we need to either get rid of the requirments from airflow core (which I believe are still there) or upgrade to newer versions of those. I think @ashb was looking at that at some point in time. Maybe it's even done already. 
   
   To be honest (and to get the expectations right) - python 3.9 support is rather low priority, I am looking at it usually somewhere between other tasks when I am waiting for CI etc.  So maybe you would like to contintue taking a look at it yourself @r-richmond ? We are dealing now with much higher priority task - speeding the tests for everyone by 2x - 6x times. 
   
   I am happy to help if you just try to run it and do some initial investigations.  What we really need to achieve is to have a CI image built with this command (--build-cache-local is there so that you can locally iterate on the image without pulling/using caches from remote):
   
   ```
   ./breeze build-image --upgrade-to-newer-dependencies --python 3.9 --build-cache-local
   ```
   So if you would like to try to build it and see if the problems can be - maybe you can try and see if those problems I mentioned can be fixed.
   
   WDYT @r-richmond ?
