Useless??  Hardly!  Surely just doing Plot[...] and then Ctrl-clicking 
is a lot easier for a beginner (e.g., a student using Mathematica) than 
to deal with a Dynamic object.

On the other hand, and apart from the issue of what to do with 
Ctrl-click when the graphics object is dynamically generated, there 
would seem to be a design issue: Now, in 6.0, Ctrl-mouse-button-down is 
the start of a zoom-in/zoom-out for a 3D graphic.
