Do you know of any compelling reason, instead of problem fixes?

Because the language is a bit archaic (has maintainability problems for large codebases, has the "too little power" problem for small codebases); as far as I have looked, the ecosystem still does not include a good templating system (although it does include most of the tools available on other web ecosystems); and the community is still heavy on applications with the same kinds of security bugs they always had, and many, many "X-only" developers.

And, anyway, fixing those outstanding problems can only make it an ordinary language. And there's no reason to look at any language that the best claim is "it's not worse than any other random language".
