I think it would, particularly as a central place to keep any
enhancements like the photon clustering. Your list of flexible features
is what I would think of. But please keep the interface relatively
clean, i.e. don't require 10 constructor arguments! ;)

I think we have a final state projection at the moment which will veto
particles in a supplied list. It might be a good idea to not replicate
this behaviour, or at least to use that vetoing FS projection internally.
