No, it doesn't. A license is just a specific type of contract. The strength is not about the language used, but the ability to take it through a legal process to enforce it. You would need to identify who has broken it, file a suit in court against them, get through all the procedural steps they'll throw at you to get the suit thrown out, then finally actually prove all the elements of a contract at trial. The precedent you are seeking would help arguments in that last step, but that isn't part that makes enforcement a challenge.
