Feature Freeze date for 17.04 is March 23, i suggest you try to workaround/disable the known bugs/todo since this sems a nice feature to get in. It can always be improved after it lands, but what lands needs to be "good" and "consistent"

> If you left-click at an annotation, it gets selected and 8 resize handles appear on the corners/edges of the selection rectangle. When cursor is moved over one of the handles, the cursor shape indicates resize mode (everywhere else on the annotation means "move", just as it was before resize feature was added). Press ESC, or click an area outside the annotation to cancel selection. Feature is only applicable for annotation types AText, AStamp and AGeom.
