Terms have meaning, including meaning derived from communities by and large accepting that a certain term has a certain semantic meaning. And the accepted semantic meaning of "Vanilla Javascript" is "runs without a framework besides the browsers own API".
If my code works out of the box in an unmodified browser, then it is Vanilla JS. If I have to load a framework for it to work, then it isn't, period. And it matters exactly nothing whether the framework in question has 900,000 or 9 lines of code.
