You also don't refuse to tell the judge what your expert will testify about if you want your witness to have their change to tell the truth.
The trial is a show for the jurors to convey information to them - everything that's going to be said NEEDS to be conveyed to the opposing side in advance, so they can prepare responses.
Surprise witnesses that blow cases wide open are only on TV.
