@TimCampion I saw some posts on Meta Stack Exchange which seem to raise this problem (or are at least related). For example: Today's change has retroactively changed the meaning of our past votes. Should we be able to change them?

Maybe it is not that important, but still I'll mention at least an chat that it is somewhat similar to this question on Mathematics: The identity/difference question. This question on Mathematics Meta is related to it: How should my question be tagged.

The question mentioned above already went through the close votes review queue, it was edited and now it's again in the reopen review queue.
