Legend
The difference is that Eberron was explicitly created with the philosophy of "if it exists in d&d, it exists in Eberron".
There is barely any lore attached to races in 5.5e anymore anyway, so their fey origin is pretty immaterial.
I think they explicitly saving the whole race/creature lore more setting books then in 2014 is why 2024 has less lore and more crunch.
