Over the years, most of my clients have been confused by the default publishing options - Published, Promote to frontpage, and Sticky at top of lists - appearing on all content types. I think it is great that these options are available in core, but I can say for projects I work on we rarely use these on more than one or two content types. I can understand how having options on the node form that aren't being used would be confusing for content editors.
What do folks think about making these publishing options configurable on the content type creation screen? The options could be as simple as allowing a site builder to enable or disable any publishing option per content type, or in an ideal world, having a UI for creating custom publishing options with the above mentioned as default options available.
