It does here also in newer homes. But just getting it into the switch and then shoving everything back in the box is a challenge. Smart switches are much fatter than normal switches, and by boxes at least were wired with hard copper that was difficult to shape. I had to take out the switch for my cabinets to make everything work.
Even a controller for a ceiling fan is a challenge. Sometimes, if you are lucky/persistent you can replace the box itself with a deeper one to make wiring easier.
I want to get a deeper box in eventually, but I have the feeling I should hire an electrician to do that, then the dry wall will have to be redone, and...maybe it isn't worth it now. Besides, I can get some good battery operated cabinet lighting to replace the ones I sacrificed the switch on.
