Today, groups cannot be assigned as the owner of any dataflows. This means, that any output of a given dataflow is by default set as the same owner. It also means that by default, error alerts are only sent to one person instead of a team.
We have a use case involving a development team who cannot be granted the manage datasets grant due to securiy permissions. Without that grant, they cannot see any datasets that are not in their name or assigned to a group they belong to. If one of these users creates a new output on an ETL they don't own, they will not be able to view the new output by default.
We'd like to be able to assign groups as owners of dataflows to alleviate these issues. It's already possible for datasets, so it makes sense to be added to flows as well.
