I believe if you build with SIP (structured insulated panels) you get these built in often - https://www.youtube.com/watch?v=PfvjvDlVzLs

Saw an ICF house a decade ago where they did some thin channel mounted on the wall & they ran everything through there instead of cutting into the ICF. Can't remember how it worked with the dry wall.

Would be nice to see interior walls built with such a thing.
