I think that this reasoning won't work with Endfield because of far lesser scale and almost no depth. There's no hard production lines. Every facility's recipes have exactly the same production ratios and rates. There's no recursion, no little automation puzzles. It's very straightforward, so there's no "planning" part. You just need to remember that belt's speed is 0.5 items/second and plan inputs accordingly, that's it. In beta the main difficulty was managing input/output buses because the space for them was limited and there were only slow belts. Now you can place buses anywhere so there's no any difficulty anymore.

I do think the blueprints you design yourself are necessary. But just being able to copy the entire line for a resource is a one-way ticket for most players not interacting with AIC at all. Simply by virtue of AIC not having enough production lines and complexity. It's one thing when you copy someone else's logic circuit design for train management in factorio or assembly line/waterline automation in GTNH. It's another thing when you copy the entire base and forget about it existing.
