Level 1 Background Feat

It looks like for Season 13 if your background doesn't give you a feat you can take a certain feat free.  There was a bit of confusions about what feats. 

As seen here:  https://purerawdnd.com/wp-content/uploads/2023/01/DDAL_Players_Guide_v13.0.pdf   

Under "Creating a Character"
"Background: You can create a custom background or
use any available background as presented. If you
choose a background that does not grant a feat, you
may choose one of the following feats for your
character: Skilled or Tough."

Under "Appendix: Campaign Worlds" 

"FORGOTTEN REALMS
The Forgotten Realms campaign comprises most past
adventures for D&D Adventurers League. The following
changes to the rules presented above are in effect for
characters attached to the Forgotten Realms campaign.
Default Setting. If it is not clear what campaign world an
adventure is attached to, it defaults to the Forgotten Realms.
Spelljammer Adventures. Spelljammer adventures are
considered part of the Forgotten Realms campaign.
Background Feats. Characters selecting backgrounds
without a feat option have an additional choice of a starting
feat: Magic Initiate"

Ebberon and Ravenloft also add the Magic Initiate feat, so I'm not sure why it isn't just listed in the Creating a Character section with Skilled and Tough instead of being squirreled away in the campaign worlds section.  (All 3 are also added to Spelljammer in an errata https://media.dndbeyond.com/compendium-images/errata/SAiS/SJA-Errata.pdf ).

So does this mean all our existing AL characters can retroactively add one of these 3 feats if our background didn't give us a feat?
