Presumably either you would add an unregistration hook when you gave the
system the clean-up it needs, or more simply you would remove all
existing entries of the form *_prompt_precmd from precmd_functions when
you added a new one and enforce that format.  Without some form of
tidy-up the question is somewhat moot.
