But do they? I've worked with clients who are, at some degree, just normal web users who now want their own website. And "how about a carousel?" is a very common request...I think that end users may get annoyed by them when actually trying to use them but as passive viewers of most webpages ("Oh there's a carousel. That's a pretty picture. OK time to do a search query for the shoe brand I'm looking for") they probably don't give them any mind...which is, of course, dangerous if you're the site owner...but end users themselves shouldn't really care because they just don't use the carousel.
