Sure, we use it in MechAssault. 

Every frame we quickly cull out any scene nodes that are not visible
from a camera, and then for each scene node we query to see if they
implement the IRenderable interface.  If they do, they get a render call.

Performance was never a problem in our case; It never even showed up
anywhere in a profiler report.
