Fair enough! I consider that aesthetic important too, and I have enjoyed playing the Minecraft Skyblock challenge for the same reason.
It just seemed to me that the mod already focuses more on preserving the tech tree and adds a lot of starting items to compensate (rather than unlock essential recipes from the start to make it more closely resemble Skyblock), so it didn't seem like a few more machines would take much away from the "starting from nothing" feeling. And it still wouldn't overcome the initial hurdle of limited land, which seems like the more important challenge of the early game to me.
... But those are just my opinions. Thank you for responding to my suggestion.
