We do not plan to add the above displayed activities to the default BPMN palette section as that section is already quite large. If you feel you need these as templates as well, simply create a user-defined palette section as a copy of the default BPMN section and add the missing templates yourself (create appropriate node, then choose "Add to Palette" from the node's context menu).
Although we do plan to add choreography templates eventually, there is no target date yet. Due to the fact that making participants work will require quite a lot of effort, this will probably not happen in the near future, though. So, don't hold your breath. ;-)
