Seems like a good decision to me. Better release a working and tested mod than whatever you could cobble up together before the first official release date.
And while I don't really have anything against lots of fighters, please make it... sensible. Large fighter battles, with lots of projectiles and particle effects, tank performance very much. And while many people question the amounts of Shivan fighters they face in The Aftermath: Reboot, I find it quite understandable. After all, it's Shivans we're fighting against. Plus it made missions a bit diverse from the Freespace standard, even if these were only escort missions.
