I disagree that your reasoning is entirely sound. It's a bit of an elitist point of view I suppose; but fundamentally I don't think all customers are created equally in terms of importance. One could even in this day and age call some of the more important ones "influencer" or something similar.

While the general customer base might not be served by this feature, what if a subset of the customer base enjoys this feature to an extraordinary extent? Maybe it fixes a lot of problems they have with the service; and negates a lot of complaints they otherwise would have posted.

Would it still not be the correct choice to "clutter the UI" with this?

I don't think it's as easy of a choice like you're trying to make it.

But I could also be jaded by the fact that Spotify for years has trying to pull me into listening to all kinds of odd European folk music that I have no interest in what-so-ever.
