Let workspace users decide whom to send notifications
Workspaces are defined by having owners, members and default notification recipients. These recipients, of course, need to be a sub-set out of the owners/members crowd. Besides that, changing the stage to "ready to publish execute" only considers owners and falling back to "editing" stage only considers editors.
This feature request aims to allow editors/users to define whom to notify, out of the owners/members crowd without limiting these possibilities on the system level.
