That's a very usual use-case.
That should use

    (read-string (format-prompt "to-list value (default %s): "
                                default)
                 nil nil default)

And if you're perplexed by the complexity of this code compared to the
one you proposed, I totally agree: we should rework our API so that The
Right Way™ is also the easiest way.
