It's because the pokemon hacking community, for the most part, is so used to having things served to them on a silver platter. It's a given, because we've been graced with so many wonderful incredible hacking tools that make it easy for anyone to hack. That's not necessarily a bad thing, I mean, no other game in existence has been made as easy to hack as pokemon thanks to the tools (though it could also be that Pokemon is an easy game to hack, but the point still stands), but it conditions hackers to have things done for them. That's really the case here, though in my opinion, I find this to be just fine, regardless of its simply being a base. It offers hackers the ability to expand their horizons in many aspects, and while a "649" patch all of the pokemon in "capturable" would be nice, this project is really quite expansive and shouldn't exist (due to its difficulty and scope.
So good work Jambo. I honestly couldn't see many other people taking up a project such as this, and it seems to be turning into quite a fine patch.
