Yes, I don't see the change will break any existing code.

> Some String params in ML are still case-sensitive, as they are checked by ParamValidators.inArray.
> For consistency in user experience, there should be some general guideline in whether String params in Spark MLlib are case-insensitive or not. 
> I'm leaning towards making all String params case-insensitive where possible.
