It is for "most web apps" because most web apps are like basecamp, and it isn't "use the latest or GTFO". It is "use the latest by default or add a single line to your gem file if you want to support older browsers."
Most web apps are only tested on the latest browsers anyway, even if they claim to support older browsers. This is true unless you have a very popular app and a very large team.
Yeah, same here. This comment thread is bizarre. I've been writing web apps that serve an industry where users don't install their software but their IT department does on their behalf: hospitals, but schools and government agencies are very similar, as well. Many of these apps are required to support back to IE8. For better or worse, that is the world some of these apps must live in.

Or you have very important and lucrative clients in government, healthcare, or some other crusty large organization with horribly dated browsers they're not going to replace any time soon. That quickly makes you throw away the latest React-* solution and reach for jQuery, however much you rage inside.
It doesn't. jquery-ujs will still be there if you want it, but depending on jquery brings along a lot of baggage along with the legacy browser support it allows. This discussion is just about what the default should be, and I don't think its unreasonable these days to aim for modern browsers as a default for most sites.
I honestly can't believe a back end framework has minimum supported browser requirements that are basically "use the latest or GTFO".
