Description
Currently, when using vectorization via VectorizedDF and the boilerplate layer (e.g., in fit and predict of forecasters), input checks are performed, even though we know that the looped data follow the datatype API by virtue of how vectorization works. These input checks can be runtime sinks in the case of large data.
A mechanism should be designed that allows to turn off input checks in the inner loop of vectorization. I suggest to start with forecasters, then with transformations.
This is a medium to hard good first issue - I suggest to spell out a proposed design here before starting to work on this.
