About RenderGameOverlayEvent and similar

You know many mods use this event to draw custom things on screen - strings, images/textures, OGL objects... It can result in HUD having these things overlapped, because I don't see a way to detect position of drawn elements from the event. Would it be possible to make a system for providing info at what screen coordinates the element is drawn, so other mods can query them and adjust their elements accordingly to avoid overlapping? Like, make an interface with getXposition, getYposition, getWidth, getHeight, so a modder can implement it and put the implementation into a list which would be in the RenderGameOverLayEvent. This way we can query this list, get positions and size of all added elements and add our element considering their coordinates.
