Consider retaining this for consistency -- it's trivial here, but I find it pretty useful for some of the slightly more involved interfaces, like PhabricatorPolicyInterface and PhabricatorApplicationTransactionInterface. It also prevents the copy/paste error where you miss one copy of the application/object you copied from (e.g., I copy from "paste" and miss renaming one instance of "paste") and then get valid code that doesn't work, since it guarantees the code is invalid until all of the blanks are filled in.
