The problem with apatite isn't that it's easy to run out, what people hate is that it CAN run out.
Sengir making this change to forestry was taking quite easily by many, thinking that try multifarms were great. They are, but non-renewable fertiliser that eventually requires maintenance, isn't what people want in an automated system, people want everything to be self-sustainable. That's why not many people seem to use oil, except from bees, because although one large spout can last you from early game to late, it will eventually run out, and require moving, and as it is non-remewable, doesn't scale well.
Previously, the answer was to use biofuel, which was 100% renewable, and one often spent ages establishing a system to ensure that there was enough sand... Water... Dirt... Etc to run forever, and always give power, without ever running out. This is now best done via MFR now, which AFAIk use considerably more power but don't need any non-renewable resources to run.
However this could all be easily solved by Binnie/MysteriousAges adding an Apatite bee - it's silly to have a bee for oil, and oil being renewable , yet biofuel not.
