It would be great if we could make changes to the schedule without the need to republish
There are - in my opinion - bigger downsides to this that need to be considered. You might want to reschedule and test the new schedule before you deploy to production. And sometimes you want to verify that the schedule runs smoothly and timely before deploying.
So, I guess the problem is really that you cannot deploy “just the schedule”. This will be addressed, as we are planning on more granular deploy mechanisms.
