I'm asking more of a technical question still;
What benefits does having Forestry 4 API support bring?
5.9 Supports it from an early changelog however 5.8 doesn't at all yet works fine (Though I imagine Bees will/are/were broken as a result but that's one of the few things I didn't test)
Recipes can and probably will be changed, but the other changes about efficiency were still nice to know about.
