This would address issues like this - http://social.msdn.microsoft.com/Forums/en-US/25b9918b-1e12-41e1-ab45-56ad53c40d10/must-manually-doubledeploy-to-get-nuget-package-restore-working-with-azure-web-sites-from-github. The BCL team has started shipping MsBuild targets as NuGet packages. With the old approach, the only way to make it work was by building twice (first build would restore package and second would actually import the restored target). By always restoring, we can solve this issue. 

Additionally, there's a couple of perf improvements in the 2.7 restore that should make restore faster in the general case.
