Well, people are still free to maintain and improve those older tools and bring them up to par with newer standards, if they want to.
Others would argue it's time to start phasing out code and so-called "standards" we've had since the early 90s in spirit of refactoring various elements in the ecosystem. As with most such efforts - lots of code will be thrown away, some of it will be re-used and re-purposed. I'd argue that in the long run - it's probably a necessary intervention.
