If you do this it will probably result in me adding an extra step to get
the last revision ID from CKAN, and incrementing it before submitting.
Extra work for me.
Is this the revision of your record or my dataset? That's a very
important detail. I may have multiple revisions of the CKAN record but
no change to the dataset (e.g. typos, or adding a new access URL)
