Well. The Actions machinery wasn't built for site navigation. So - as 
you describe - it's hard to use Actions that way.

My prototype has plugin support for custom ActionCategory objects. If 
you want to use the ActionsTool for site navigation, you could write a 
customized ActionCategory class that returns dynamic actions.

On the other hand I just propose to replace Action providers that use 
ActionProviderBase by a new centralized Action provider. Removing the 
possibility to register other Action providers is not part of my proposal.
