Third party intergration windows phone

Now that Windows Phone has a fully functional Facebook and Twitter app, there is no reason to keep the "What's new" new section from the people hub. Other then the fact it acts as an aggregator, which could be easily be replaced by an app. An app could be updated much more quickly and swiftly than a system update that would be required to fix the What's new section.

This kind of integration was originally a differentiator for windows phone, but it would appear this kind of system integration of third party providers has been replaced by apps.

What is everyone thoughts ?
