Hello all, this is Justin from the PM team at Databricks. We are sorry about the friction this caused you. This was a feature related to the new way that we are doing dependency management in our serverless offerings - Environments. We are going to re-vamp the feature a bit so that it is not causing phantom diffs in your notebooks like this. I'll have some more updates in the coming weeks.

If you are using our Serverless offerings with repos then please email me (justin.breese@databricks.com) if you're interested in helping us shape this product area.
