Yeah, but I’m Jewish.
I’ve never gotten an entirely satisfactory answer on this either. But there’s even an old tale about two of the great sages arguing over a particular point of Jewish law. One has cites from the rest of the Talmud. The other sage knows he’s right, but he can’t prove it. He says “If I’m right, that tree will get up and walk.” G-d makes the tree get up and walk. The other sage says “A walking tree is not an acceptable cite.” This goes on for a while. A river leaves its course. The walls of the house bend inward. “These aren’t acceptable cites!” Finally, G-d talks to the sages. One sage says “You see? I’m right! G-d is my cite!”. The other sage says “G-d is no longer an acceptable cite. He told us so when-” and he cites a passage I can’t remember. The Lord finds himself unable to defeat that argument. He returns to heaven laughing and saying “My children have defeated me.”
So we can interpret the Torah. We can do research to make sure our translations are accurate. We can weigh different verses against each other, or combine them. We can try to discover what the Torah says about modern issues. But, we can’t add to it.
Back To The OP
From the above Jewish perspective, waving the waiting period makes no sense to me. If somebody was truly virtuous, blessed etc I’d think people would still remember them after five years. It seems to me that the waiting period is there for a good reason. Waiting allows a more objective examination of the person and for a thorough review of their life. Instant canonizations would result in people being made saints simply because folks miss them and people got caught up in all the nice eulogies. It might also result (Note that I am NOT suggesting that this is the case with John Paul the second) in some one being made a saint a few months before somebody cleaning out the deceased’s study finds the stash of home movies featuring their long career as a serial killer.
What’s the point of a devil’s advocate saying that the person isn’t a saint, and skeptically examining the miracles for scientific explanations if the Pope rushes the process while hinting that the candidate is a saint?
