There is legacy v0 endpoint used mainly by the UI. The core feature needed by the UI is - be able to push schedule and job definition at once. Ideally we would like to get rid of v0 endpoint.
Document differences between v0 and v1.
Propose a way how to move from v0 to ONLY v1 (ideally without too much work).
Find out how much work that would be on the UI side (ideally we should just change v0 to v1 as string, run tests with good enough test coverage and be done).
