Thank you for actually looking at the practical effect of the suggestion. I️ agree that the suggestion removes EEPG as a +1. Good riddance. XGE reprinted most of it anyways.
That would leave the choice between SCAG and XGE. That is a fair choice, IMO. SCAG is no slouch because of Greenflame Blade and Booming Blade, the cornerstone attacks of most low level Gish builds. While I️ love those spells, it is perfectly reasonable to say that all future subclasses and feats should not have to be designed to play well with them.
I on the other hand think we would let WotC awfully easy off the hook if we can't even expect the little crunch they have offered for this edition to work well together. It is perfectly reasonable to ask that all future subclasses and feats should be designed to play well with Greenfire and Booming Blades.
(That has, of course, nothing to do with the AL. And since we're in the AL forum, let me move on to my next point:
As regards the AL "+1" rule, races have seldom been part of abusive combos, so I'm not sure we're doing ourselves any favors on focusing on them, in their abusive potential. (I do understand why they're the focus of this thread...

)
To be honest, I would say that the main reason for restricting races is to keep the rule simple, and in order to avoid having to create exceptions.
In other words - not what Remalithis is noting. It may be true that exempting races would essentially nullify the rule, yes,
for the moment. But that loses sight of the bigger picture - which is that races seldom make enough of a difference for a combo to be abusive, and indeed that there aren't really any abusive combos that justify the rule.
Yet.
The main reason for the overall +1 rule is instead to safe-guard against future splats and future powercreep. The fact this took way longer than in previous editions (and arguably hasn't even happened yet) can't be taken to mean the rule is useless.
Unless I'm forgetting something, races are mostly just an incidental casualty, rather than the focus of the rule. (As an absurd example - I can't believe Pun-Pun, say, depended on an otherwise-AL-allowed racial Kobold ability)
