    Question: How will users see/detect/understand this behavior? What will they
    see in "Show initial Lisp expression"?

They will see an expression that recomputes the standard value
based on whatever conditions are relevant.

My approach, like the one Luc's original one, avoids the need
to complicate this with fboundp's or condition-case, but someone
still needs to determine what all the conditions that affect the
proper standard value and write an expression that chooses
among them.
