That sounds a bit harsh considering the bunch of work of such bundle.
Looking at Alienheretic models you can see that the models almost all fit together quite well.
Maybe, the interested people gives him hints which sort of models would make his collection more complete in respect to an all-in-one bundle.
Maybe, someone pays for such a bundle a non-exclusive price to get Alienheretic started, and after that he can sell it to the broad audience.
Your requests sounds a bit as if I ask you not to sell such helpful assets like seed_it, but a complete set of features for a fully working game!
