Hi Michael.  I appreciate you CCing me, so no need to feel sorry.

You should be able to specify the :value property directly, rather than
overriding :value-create.  Something like:

(widget-create 'editable-list
               :value (list my-first-default)
               ;; Change according to the child type.
               '(editable-field))

Does that not do what you want?
