The assumption is that hyper-parameter tuning uses Pipelines, I think.
You want to select all steps in your processing, which is rarely just a
single model.
However, Pipeline can currently not change the number of samples (see
the enhancement proposal Gael linked to).
So you can not use your methods in the standard scikit-learn pipeline.
