The only place so far that I found in RCP apps where you must use
actions is some of the Workbench build in actions.
I.e. While it easy to replace exit and preferences action with
appropriate command. I haven't till now found a way to replace the Help
Action. (though probably one just has to contribute an appropriate handler.)
Though on self implemented stuff I have never seen an ocasion to look back.
and if you ever need to create commands on the fly with full control
over anything and you seem unable to do with declaration from plugin.xml
there is still the CompoundContributionItem.
