Ya, I can't imagine one of the npcs we have now getting swapped to a dwarf/gnome/halfling just because we don't have one is just plain dumb imo.
Definitely not what I was asking for. That would be silly. But having some more companions (which we're pretty sure we'll get) and having at least one of them be of a small race would not be amiss.
Edit:
And while your opinion is freely your own, I personally do feel it is a problem when certain races are only NPCs. It gives them a sense of "otherness," for lack of a better word. This makes them feel like, well, inconsequential NPCs rather than a fully incorporated race - and for me this feeling then extends to any character I desire to make of that race. Having a companion who you get to know a little better than your rando NPC makes the world seem a little more complete when I play a game.
This doesn't really extend to monstrous races who wouldn't make any sense to be running around with all the other player races, so goblins and ogres are fine as-is.
