Bahamut is unmentioned. I might have suspected that the Dragonborn insertion into the Forgotten Realms setting, was being targeted.
While Bahamut is unmentioned in these books, he has been mentioned in all the relevant books lately, including the 2024 DMG and The Book of Dragons (that includes a lot of updated Realmslore for dragons). So, he still exists in the 2024 "canon". He and Corellon aren't given the spotlight in the new books because they are not part of the Faerûnian pantheon, just as the Egyptian gods are just name dropped in the Mulhorand entry and nothing else (including the non-accurate "Horus-Re" name that gives me OCD, lol).
The only one who seems to be completely non-canon for 5e is Enlil, as he is not mentioned in any of the 5e sourcebooks (not 2014, neither 2024). But, this kind of makes sense, as the novels he appears in seem to have been ignored in the new books.
As for the other stuff, it seems that 5e 2024 is kinda deemphasizing/sanitizing the religious aspect of the gods, but that's with all gods, not just the racial ones. Even the entries in the 2024 DMG are scarce.
