The only thing missing for positioning is that Rotate and Scale had sliders whereas the new one does not. Sliders are limiting as they have an inherent minimum and maximum. Think about someone making a horizontally scrolling ticker- or TV-news-like text. That needs to be very wide depending on the length of the text. That means the X position value for some keyframes needs to be very large - larger than Rotate and Scale’s Offset X parameter’s maximum (or less than its minimum).
The new filter has more options for positioning including dragging. You do not need sliders. If you want to change a position value without dragging or typing a number, then you can use the mouse wheel over the numeric fields. You can also use Up and Down when the field has focus. The next version 20.10 lets you drag from anywhere inside the rectangle when you hold Shift.
