Airflow has come to a very weird place where providers shows code lines that can never be used due to key functionality is missing in official airflow releases.
In that example this renders behavior was added to BaseOperator but was never released.
#11061

This resulting in us users saying "wow this is cool! lets try this" only to eventually see that we can't because the core feature wasn't release in any official version.

For me it looks like a case where the extension pack of a game is released before the game.

@RosterIn this will be part of Airflow 2.0. We do not cherrypick every change to 1.10 line, so this change is not unique :) But I understand your disappointment. We need providers to ease migration but we also needs to move on with new features. What would you suggest to do?

[github-actions]

The PR should be OK to be merged with just subset of tests as it does not modify Core of Airflow. The committers might merge it or can add a label 'full tests needed' and re-run it to run all tests if they see it is needed!
