These things won: React, Webpack, Jest. They've been the dominant tools for years. (Typescript is getting there.) The ecosystem around them is enormous; a million edge cases have already been handled; they're not going anywhere for a long time.
It's not really a surprise that as browsers become more like operating systems, people will experiment and find new ways to leverage the available capabilities, but you don't have to play with the new toys, and you definitely don't have to use them for paying work. Just say "risk" ten times if anyone suggests them, and your PM will end up agreeing with you.
