Looking back at it, I think now the idea was that passwords which
have been the same for too long are more likely to have been
guessed/stolen. My original interpretation was that RP's would care
if an OP said "This user authenticated with a password that was
changed five minutes ago." (indicating that the attacker had tried to
lock the legitimate user out of the account, and was then trying to
exploit their stolen account before the user found out and reported
it).
