I feel it never really was about denying how effective plain web pages are but rather that faced with the choice of a wonderful DX with just JS, and a more difficult day to day with a mix of both, we picked the first. Sometimes at the expense of the end user, yaddi yaddi yadda, etc.
Good solutions for the "have your cake and eat it" scenario with exceptionally good DX are just now reaching some maturity.
The only real downside of HomePods is that they don't function as bluetooth audio receivers (Apple proprietary AirPlay2 only) and that you need an Apple ID (as well as iCloud enabled on that Apple ID) to set them up - the creation of which these days requires a working phone number, so it's a little expensive (burner SIM) if you want to buy and use them anonymously.
People commenting about how Siri sucks I think are missing the point of these. These (presuming the sound quality is similar to the HP1) are the best consumer self-powered speakers for under $2000, full stop. The fact that they do anything else (mics, voice assistant, wifi streaming, whatever) is mostly unimportant if you understand what these things are. I'd use them even if they didn't have Wi-Fi. As far as I can tell, they (and airpods) were the latest "insanely great" product Apple made until the M1 macs dropped.
