Sorry, which of these did you have in mind?

Option 1: move the Filters integration tests under a new `mvc` package in `framework/src/play-integration-test/src/test/scala/play/it/`. 

or

Option 2: move the Filters integration tests next to the unit tests in `framework/src/play/src/test/play/api/mvc`?

Option 1 seems like the right place for integration tests, but option 2 would actually keep the tests in the "same SBT project" as the code for a quicker dev loop.
