It's niche but used enough in the industry to give us tools like Coalton (https://github.com/coalton-lang/coalton/), used enough by hobbyists to give us nice new libraries (new TUI library: https://github.com/atgreen/cl-tuition/blob/master/examples/R...) and exceptionally good and fast open-source compilers (SBCL) (with a good bus factor and contributors from the industry, like Google), it has enough libraries to allow us to ship software to clients (web clients, web servers, web UIs (webview, webui), SQL libraries, etc). It's niche but the motivated developer can publish a game on Steam (Kandria).

(btw, ABCL has the benefit of Java libraries, for those interested)

Julia has its own issues (and isn't on par outside of scientific area).
