Seems that Revit have to pay more attention to the CDs part of it.
When you do a lot of long wall sections, like the ones of a high skyscraper, you play with the design of the viewports where you are going to put these wall sections and go back and forth with the different sections on the different viewports, like when you are designing them, until you get a layout that you like. The notes have to be configured (i.e., moved, relocated, etc.) many times to help achieve a desired layout, and if you have the annotation crop visible all the time, then that will help the process (hey, and you do not lose the notes because you can see all the times, on the spot, how much space you have and how much you can move the text before that happens). This is just one example of why this capability shall be possible for those who want to use it.
And regarding the CDs capabilities of Revit, which have room for improvement, and you have a long wall section that you need to break to put the most important things of it on a 24 inches high sheet (and use view breaks and break lines), have you noticed how difficult and laborious it is to deal with two adjacent "break lines" and their masks when you want to have "minimal" distance between these two break lines?
