Inside Microsoft, I've heard the phrase "we should build a pit of success" which means that the first way you try to do something should be the simplest and easiest and should also be one of the best ways! You should fall into a pit, rather than climb a mountain, and that pit should be filled with gold and/or other goodies. It also means that people should stumble upon things that will help them be successful, they shouldn't have to go looking for them.
With that in mind, I'd like to see something such as Mander's Safe Area Component and other useful tools (screen shot button, FPS counter, etc) find a more prominent home in XNA. Maybe for debug builds we could hijack one of the F-keys for a debug-tools menu. Developers are sure to stumble across them sooner or later :-)
This also reminds me of this feedback item for Game.TitleSafeRegion (closed external? too late to vote?)
And lastly, a lot of people (myself included) are creating high score games and integrating the game state management sample. Maybe a template for "New High Score Game" in VS would safe many people a great deal of time while tricking people into respecting title safe regions?
