That's a big if. I'm not convinced suppliers genuinely attempted to provide useful RSS feeds. Even during the hay day of RSS, many feeds were simply stubs meant to get me to their website—even for websites to which I was already paying for the content. Regardless, demand for a particular solution is much different than demand to meet a particular need. To suggest RSS is 'obsolete' suggests its been obviated by a technology which meets the same need. I don't see that as being the case. It is far more likely to me that RSS doesn't meet the needs of the supply side. Solutions can also be dropped for lack of profitability or other supply side concerns even where demand for that particular solution is high. You can see this in action today. Ask yourself why Spotify doesn't support RSS for its podcasts despite it being extremely popular for fetching podcasts.
