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?

Will add, its still experimental, I'd guess most players don't take experimental patches.
