The IDs are not needed to play, aren't displayed in game and wildly divergent IDs have bordered each other since release (and did so even in EU3 which is the map ours was based on back in the day). I agree that for modders and people who want to use the console renumbering the 4000+ provinces in the game would have some use.
The major cost of it would be that every save game in existence would break completely though which makes the entire thing very unlikely from our point of view even if it didn't also mean revisiting hundreds of events and decisions
