r.terraflow is a critical piece of our r.landscape.evol script (GRASS Addons/LandDyn) that models long-term surface process dynamics. I sincerely hope that we can solve any licensing issues or have it replaced with a better module. There is nothing else in the GRASS repertoire that actually replaces it.
