Re: MVP Pattern Without History Mechanism?

This is an anti-pattern.

You should make sure that all screens that can be navigated to by the user are stateless in the sense that all the state can be derived from the URL. 

The big advantage is that the screen can be bookmarked users can navigate to it directly.

If you are concerned about redundant backend calls encapsulate the backend calls in a seperate (singleton class) that handles caching. This will also reducate the logic in your Presenters because you don't have to check the URL parameters against the already fetched data.
