Anecdotally, from a programming support community I hang out in...

i've never seen anyone promote the values of Clean Architecture in the practical world. The only reason I even know about it, really, is because it's a pretty popular topic for amateur/beginner developers to come in and ask about, because they read a book or a blog article about it, or are being taught about it in a class. And the response is always, universally, "Don't use Clean Architecture, use Vertical Slice Architecture."

I get the vibe that it's been popularized in the same pattern as microservices or lambda functions: someone at a super-scaled company like Google or Amazon published a blog post about it, and how it works for them for some niche scenario, and everyone latched on to it as trendy, despite the fact that their scenarios are NOTHING alike
