Keeping up with JS libraries APIs is a very thankless task. Most companies use a certain version of e.g. NextJS and when it’s good enough already, they don’t change anything. I myself maintain rescript-mui where I did not even finish all the bindings for v5 and now v6 is the most recent one.
But at work we still use v4 in some places so there is no incentive to do it. But it helps that the library is out there and people can copy it into their codebase and adapt some small things so it works for their use-case.
Ideally we want to have a best-effort bindings repository where some tooling helps you copy to and paste from it, but nowadays it feels like people just use an AI anyways so not sure if it is even worth the engineering effort.
