Sorry for the late review. I just have initiated a discussion inline on the placement of Airflow version check conditionals. Please check

I feel it maybe better to introduce these conditions in the respective method instead of adding the conditional here and in those methods based on the Airflow version, for now we could decide on whether to call the inner function or not. Later on when we add support for AF3, we could call Airflow version specific inner functions within those functions to handle both versions. WDYT?

I thought it, but I found this approach easier for handling decorator calls like provide_session. However, I'll give it some more thought and, if possible, will create a follow-up PR.
