I guess that will depend on user feedback. Implementation of such a flag 
should be no big deal, but I currently don't see what it would be good 
for; it would also open up the question how the flag should actually 
work: For instance, should it affect only interaction with photons 
/before/ the target, or also /after/ the target?
