When Eberron officially became part of the 5e multiverse, the gods of Forgotten Realms became factually existent.
But this then raises the question. Yes there are powerful Astral creatures. But are they worthy of "worship"? Do these creatures even want to be "worshiped"? Perhaps some or most dont. It is possible to remain nontheistic despite factual existence. The Greekesque Theros setting explores this via the Iconoclast. It is the Buddhist approach as well, with the understanding that if gods exist, then they lack personal enlightenment. The Planescape and Sigil setting has room to explore this philosophical question too.
With 4e and 5e, the Eladrin relocated from the Astral to the Feywild to function as Fey beings. Probably, the Norse nature beings should as well, specifically inhabiting the skies of the Feywild and looking down at the Humans below in the Material Plane that the Plane overlaps. The Norse world tree Yggdrasil remains canon in 5e 2024. In Norse cultures, this tree has three roots. One leads to the region of the dead in the underearth comparable to D&D Shadowfell, plausibly one root leads to the Feywild sky above, and the third root leads to the realm of the þursar, a kind of Giant, possibly in the Ethereal Plane. These are shamanic concepts of nature-oriented animistic cultures.
The overall point is, in D&D powerful creatures exist. But it is human opinion that decides if these should get worshiped or not. Many cultures lack the concept of "worship", which assumes the cultural structure of a lord/servant relationship.
