I'm going to suggest that we not change that.  there is a value to parallelism - in the app classes themselves, the class decorators add attributes to the classes using this template: ```{resource-name}_connection_factory```.  For postgres that expands to ```database_connection_factory```.  This attribute in the Crontabber class serves the same roll as the attributes in the app classes.  Having the name the same in both places has an aesthetic appeal.
