Thanks for looking up the detailed answer. It is likely still
accurate. The problem with the object property approach is that without
a reference to the symbol (like some data structure containing it, or
some code referencing it), the object property is volatile.
So if you use this sort of define-object-property before storing the
symbol elsewhere, it will evaporate at next garbage collection.
