The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

I also think that the Patch/Delete endpoint should be added alongside this endpoint to make a complete CUD

Indeed, I’m already working on PATCH and DELETE, but want to post this first since it’s more or less standalone, and after this the rest is very straightforward. If it’s desired, I can continue to push to this PR instead.

Yep. Pushing here is cool in my opinion

I’ve added PATCH and DELETE, but left out the AUTH_USER_REGISTRATION check. The documentation says it toggles self registration, but this API is intended to be used by admins to create a user, not for new users to create themselves. So the endpoint shouldn’t be disabled by the configuration IMO.

Please rebase on main since pylint is removed now :)
