Uhm, well not really. Having something like

Context c = ...
<add view-specific context menu, for example for projectmanagerview>
emit(c, list);

And then suddenly the list is changed is a bit too much magic for my
taste.

You misunderstood. The QString will create a new menu entry, the same
way the subversion menu is shown in KDev3.4. Then within this new menu
entry the list of qactions of that plugin will be shown. And the
qactions need to be connected to slots of the plugin of course.
