Yeah, the two things aren't even in the same category in a mechanical sense. Backgrounds are almost wholly inconsequential mechanically in Adventurer's League: probably the most consequential one is the Acolyte background, and even that background's effectiveness is highly dependent on season. Races aren't remotely in the same category -- they provide stat bumps which lead toward specific class choices, often provide spells or other special racial abilities, and some even unlock specific subclasses. The two are not comparable. If there were a class for which a specific background is not only a 'must-take' option, but any other option is sub-optimal, then I'd be willing to reconsider, but that's simply not the case.
With that said, I am feeling a bit of sympathy for those characters who have the EEPG as their +1, since most of the classes and all the spells are now going to be re-printed in other books, which will generally be viewed as superior choices of +1 resource. (I'm not sympathetic enough to want the admins to actually do something about it -- those 'early adopters' got their benefit at the time, after all -- but I understand how those players might have a legitimate complaint now.)
