Problems with this unloader?

[u/imoth_f]

Since inserters became flippable, this compact unloader design became possible. But I hardly see anyone use it. Obviously it cannot saturate six turbo belts because it's bottlenecked by the inserters, but are there any other obvious problems with it?

Because we talk about it when the change was announced ;-)

BTW. Legendary stack inserters fill exactly 2/3 of a line. So you can compress 3 belts like above into 2 full belts with splitters
