Here's a thing... There's been many of them and they all die because they don't provide enough benefit over the status quo. Cyclone https://en.wikipedia.org/wiki/Cyclone_(programming_language) is probably the most known one. There's Safe C https://www.safe-c.org/ A bit further from just "dialect" there's OOC https://ooc-lang.github.io/ and Vala https://vala.dev/

But the only thing that really took off was effort to change things at the very base level rather than patch issues: Rust, Zig, Go.
