I'm sorry to be the pessimist here, but I doubt it. HN users are the most likely to use RSS in the first place. I sincerely doubt that RSS is going to make a comeback this year with all my non-IT friends using it.
Realism shared. I work with journalists, exactly the type of normies who would most benefit from this technology. Years of evangelism has had no effect whatsoever. Nobody they know is using it, they don't see the logo anywhere, or a big friendly "Get started" button. It's all so unfamiliar and technical-sounding. Even the name itself was a disaster, IMO: a hopelessly geeky and opaque acronym. It should have been called Webfeeds! It's all such a wasted opportunity.
In this case having more people asking for it or expecting it can contribute to expanding the availability of RSS feeds to more websites.
While the vast majority of technical stuff I follow uses RSS, the same cannot be said for some other resources I like to read.
While some are kind enough to enable them when asked, I don't expect them to want to support them for just a handful of people in their target audience.
Honestly that might be for the best in some ways. I see rss as "allowed to exist" because not enough people use it. There's plenty of ways to subscribe to things that I enjoy right now that could be nuked if suddenly enough people were using it that they weren't seeing the conversion rates they wanted.
