How so?If the given justification is the reason behind the background restrictions, then it doesn't make sense that some characters of those races are exempt from the restrictions. Either the goliath and aasimar restrictions should not exist (and thus would not exist for all characters of those races), or all characters of those races should have to abide by them.
The restrictions weren't created out of concerns for these particular races - they just get swept along together with all the other Volo races.
That is: having an Aasimar or Goliath enter town didn't make the villagers bring out the pitchforks before, so AL doesn't remove that choice. Just pick a different +1 than Volo and you can keep not having to explain their presence.
An Orc not so much. (Although had a previous source offered background-less Orcs, I'm sure AL would honor that offer too)
I was going to ask "how can you treat VGtM and SCAG as a single source", but now I'm thinking you mean:Correct. Though Goliath and Deep Gnome can be picked from two different sources (EEPG or VGtM/SCAG respectively).
Goliath can be picked from either EEPG or Volo.
Svirfs can be picked from either EEPG or SCAG.
