Minimal Lisp binaries

Nearly all lisp dialects have native code compilers, and many can produce standalone executables. One thing I don't understand however is why executables require the full run-time? especially when your code doesn't use eval. Is there a way to use create a minimal image with sbcl that only includes the functions your program uses?

Come fucking on, you'd have to tie your dick in knots to make executable code have a noticeable footprint on a modern machine's memory or cache. Data take up much more that code. I've never seen the size of a binary be a real performance concern.
