I think that honestly, a lot of the resentment players here are feeling for gnomes and half-orcs being non-PHB1 and dragonborn or tieflings being in PHB1 is that DMs who took a hard line of banning all non-PHB races in 3e had to have been widespread, considering the amount of players (including myself) who have complained about that being a frequent condition.
I know *I* don't, but it seems pretty unfortunately common.
You hit the nail right on the head! I'm a wide-open DM personally, but the majority of the DMs in my group don't go outside the PHB. Heck, several don't even allow non-PHB base classes, though typically gear, PrCls, Feats & spells are OK.
Honestly, though, I don't think it will affect the hardliners. The same DMs I know who excise non-PHB races also do things like ban classes they dislike- typically Paladins.
Oh, and the <bleeping> planetouched (aasimar, tieflings, gensai, etc.) are getting changed to some sort of damn template instead of them being distinct races, like they always should have been.
I'm doing that myself, using the term "Nephilim." (http://en.wikipedia.org/wiki/Nephilim)
