I dont disagree, however, I have not used that tech tree mod in a long time myself due to running my fixes mod which altered many recipes and broke advancement with that mod.
tech tree is kinda a long-term goal thing, right now as it is much of the recipes still need some rework to for balancing reasons and I'm going to get Space Age support directly into the mod once things are more stable. This also means more recipe changes if SA is detected to make things more progression based.
