I'm so NOT a fan of the idea of removing any meaningful differentiator between races.
I'd rather see way to make alternate builds more viable (i.e. DEX based barbarians and so on).
Once Larian implement rolled stats (and they promised! :P ) ...
Racial Ability scores become much less relevant ... if all it takes to start your Halfling Barbarian with 18Str is few rerolls ... then just reroll few times.

That's not entirely true.
Any race with, say, a +2 STR will still able to start with a 20 in STR after rolling a 18, which is not an option for a race with no bonus on that stat (sorry, ABILITY).
