Oh, most definitely.

Several months back I was kinda pulling my hair out over the frustrating state that Apache Airflow was in, because (due to my company’s infosec, SQA, and regulatory policies) I found some delightful mutually-exclusive transitive dependencies when I tried to diverge (with version upgrades to get past CVE-marked releases) the constraints from the officially-packaged constraints.txt. Though, that’s packages, not actual lang level.

Were you around for the 2 -> 3 migration? Now THAT was a categorical shitshow.
