Like I've already said, The stool coding he mentioned has cool value elsewhere for simulating the act of standing on a table or statue, so it seems a better choice to code in anyway since it'll have value down the road.
I suppose an issue is how the stepladder code works. Will the dwarves simply automatically decide where to place the stepladder, harvest, pickup and repeat? I doubt he'd have us constantly have to designate a stepladder area for them. But then how efficient is it to scan for areas which would yield obtainable fruit above the square as opposed to just increasing the range around a dwarf for picking? On a steep slope you could have situations of reaching horizontally outwards to obtain fruit.
Also unsure if you're poking fun at me with "expert long form description," but I don't know how else to describe a pole with basket on the end, and a convenient picture attached.
As for affecting gameplay, you're right, it wouldn't affect much. Maybe depending on how they're created and carried, which workshop they come from, material they're made from, amount of material required for construction, speed of harvesting maybe. Overall not much changes from one to another in that regard.
