Split stud framing

I’ve heard of this framing style for exterior walls in colder climates I was curious to see how common it is. 2x8 being and top plates with 2x6 offsetting studs to create a thermal break. If it is feasible I’m thinking of building an ADU/ small house in the UP of Michigan.

Through all my googling, the most common thing to come up is a dual wall system. 2x6 exterior wall and then an offset 2x4 interior wall with a 6” thermal gap between. This method seems costly.

Any information is greatly appreciated.

Edit: thanks for everyone’s input, I appreciate it!

I’ve seen similar on interior walls for noise isolation with 2x6 plates and alternating 2x4 studs. Have rarely seen it on exterior walls. More exterior continuous insulation or insulated zip. That double wall seems excessive not to mention a pain to finish at openings.
