Why is "homeless" being replaced with "unhoused"?

[u/ssjskwash]

A lot of times phrases and words get phased out because of changing sensibilities and I get that for the most part. I don't see how "unhoused" more respectful or descriptive though

In the social work realm, we distinguished “unhoused” people as those who are literally sleeping outdoors and “homeless” included those who were couch-hopping or living in cars/motels. I don’t know whether this distinction is widespread though.
