Verilog ? Its far far more primitive than that. You'll find exactly that arrangement in prehistoric 8bit micro support chips - eg the 6522. In fact the only reason I can see for not using it on primitive 8bit micro devices is that they *already* had more features.

No they are implementing trivial common sense logic. It's a bit like complaining we have multiple drivers that use addition.
I think you need a reality check. Its a VLSI undergraduate project level device, or was back when they taught undergraduates a sampling of chip design by drawing the transistors. This is "my first logic design" stuff.
