I'd say it has lost some meaning, but a change of 2-3-4 players doesn't change the summation that much in most cases. It might make the A&M figure really less useful.
The list is probably still a decent one in terms of overall talent on leading teams. (Another factor is where the talent is positionally of course. If you happen to have 4 four star tight ends and three 4-5 star QBs, it means less than having the stars more evenly spread through starting players.)
