Well a diff app will stay relevant and there's always people using it. It's not a one time thing that becomes outdated! :p well yea the XY concern is definitely there. I suppose even if emulation doesn't come, smogon will have to use bw mechanics first and try to reverse engineer till it's finally emulated ;o if rng can't be done for XY, VGC and stuff are going to be badly affected; idk if nintendo wants that. :o
