I was bitten by this as well.  But I can understand the rationale
behind the change.  The old name made little sense.

Actually, I recommend going even further: add new methods
called GetTypedValue() et al. and deprecate GetValue() et al.
Then, for VTK 8, I would love to see these method appear:

  double vtkDataArray::GetValue()
  vtkIdType vtkAbstractArray::GetNumberOfValues()

I would really like GetNumberOfValues() to make a comeback.
