Yes they do. God, how did you (and apparently you're not alone) read my rant and still got it 100% backwards? I specifically hinted about not picking a single aspect of a language - REPL or whatever. What is so confusing about my wording on "holistic, overall experience working with it"?

And it's false. There's nothing special about a REPL in a homoiconic language. Homoiconicity has nothing to do with a REPL or tools.
I do however think SBCL has a very nice environment with great tools (especially it's compiler) and that's why I've used it a lot over the years, but I really think you underestimate the environments in other languages (including the "holistic, overall experience").
You are wrong. You might be correct about the workflow but still wrong about the semantics. Pedantically, your notion is false, because homoiconism gives the REPL a genuine capability (program-as-manipulable-data across the read/eval boundary) that non-homoiconic REPLs lack.
