The problem I see with this suggestion is that a character with racial boni / abilities & a feat at level 1 seems a bit overpowered. I know some people here like that, but I'm not one of them.
Also, it would make the variant human (if Larian implements it) obsolete.
How about postponing it until level 5 then? It doesn't have to be at level 1.
Or we get to choose a free feat when we reach a specific milestone in the campaign. Maybe 2-3 times.
