Drupal 8 now includes two Symfony2 Components: ClassLoader and HttpFoundation.
ClassLoader provides support for the PSR-0 autoload standard.
HttpFoundation provides useful abstraction objects for the incoming HTTP request and for the outgoing HTTP response.
See the announcement blog post for more details.
There is an ongoing discussion of other Symfony2 components that may prove useful to Drupal as well.
