Wrong gateing of intermediats

[Chaoschaot232]

In my playthrough, vanilla and modded, I noticed that

factorio-deadlock-beltboxes-loaders/prototypes/shared.lua

Line 25 in ac47853

[2] = { "copper-cable", "iron-gear-wheel", "iron-stick", "sulfur", "plastic-bar", "solid-fuel", "electronic-circuit", "advanced-circuit" },

gates cables, gears and rods at the 2nd stage but why?

This is wrong gating for stacking because you have access to these materials quite from the start which means that you should also be able to stack them after unlocking "Stacking 1".
