This has been a thing in most DnD video games I've ever played; because they want to provide a large sample of races for players to pick, but they also don't want players to be stopped from... you know... actually playing the game.
In NWN2 I think I remember all of two lines dedicated towards being suspicious of your drow or deep gnome, or grey orc, or yuan-ti, and then the rest just played out the same as it always did. The only difference was with the yuan-ti, and the storm of zehir expansion, you could get "discovered" to be yuan-ti by roaming patrols on the overworld map, which would then attack you. But I just treated this as free experience, it didn't really have any effect on the story of the game.
