Since it USE's COMMON-LISP and it's the package SBCL puts me in with the REPL I kind of figured it was the most appropriate choice to use in my own packages. I wonder if it used to work in some other implementation.

CL-USER is a package that USEs COMMON-LISP, not a package that exports the symbols of COMMON-LISP. I don't think CL demands that CL-USER doesn't export any symbols, so it's possible some implementations decide to make it export interesting things.

BTW, this would be a good thing to note in a tutorial or best prectices for package management, if someone is about to write one...

Here's another good thing to know, in case you want to write CLIM applications: don't USE the COMMON-LISP package, USE the CLIM-LISP package instead. You still have to USE the CLIM package and anything else you're interested in.
