Hey everyone,

Just wanted to ask if there's any interested in adding Flycheck (https://www.flycheck.org/en/latest/), a popular alternative to Flymake, to NonGNU ELPA?

You can find the codebase here https://github.com/flycheck/flycheck
There's also some integration with Eglot https://github.com/flycheck/flycheck-eglot

I'm not sure what's the stance of adding alternatives to built-in packages in general, but I think providing some alternatives to the end users is not a bad thing overall.
