I don't know the current policy of Wikidata regarding changes of concept
definitions, but I guess one would need to do the same for all
completeness statements that one would need to do for all regular facts
that use the modified concept: Recheck whether they are still valid.
I would actually create a new Property and rename it to a name that was
still appropiate (eg. 2005 planet).
Which is still interesting since
(a) IThe old property is probably useful per se (albeit the new one
would be more desirable).
(b) Either the new or the old term is probably a super set of the other.
PS: The opposite can actually be considered true: The several legitimacy
acts in England "changed" what was a "son".
