Doesn't most of the programmers program to a particular scheme or lisp implementation(sbcl, racket, clozure, gambit, clojure)? Common Lisp libraries seem to be getting much more portable across implementations, so within the CL dialect the language implementation is becoming less of an issue I think. And QuickLisp is one counter point to the OP -- it has broad community support.
