I don't think these shorts were meant to be anything beyond just a little bit of fun they can share online and at the con for our patience during this hiatus.
But you may be partially right. They could be an experiment of different formats for the show itself to garner a possibility of a future incarnations.
I personally liked the Auman short as a potential anime version of the series as opposed to the two part ova that was unleashed in Japan years ago.
