Rolling abilities is still extremely popular, there is some debate whether or not it is the most popular way of generating abilities, but whether it is still the most popular or not, it is still very widely used by tens of thousands of players and won't be eliminated. So anything that replaces current ability scores has to come with a method of random generation.
I do wonder if its more common to roll, than with Array or Point Buy.
(If people are rolling, then any discussion of 'balance' can be thrown out.)
