I used to run summer and winter tires on my old Mercedes diesel (rear drive). I have a driveway, a garage, and tools (including air tools) and it was still a pain in the ass.
People without that need a place to store 4 bulky, dirty, heavy tires, and a way to get them to/from whomever is going to swap them. People who live in an urban setting would likely find that pretty annoying.
I also drive so little that one set of tires ages out before they wear out. Now, I’d have twice as many tires aging out, which is an economic and ecological problem of its own.
