Also, that footnote implies the exact opposite of what you said - it was the Men who thought that Morgoth was yeeted into space, while most of the Elves knew better.

the question seem sto be what better knowldge the Elves had? And one probabilty is that the Elve believed neither in Melkors fëa been pushed out of the Kingdom of Arda (into Space out side the solar system, that would mean) nor that he was removed from Eä by an direct intervention of Eru, but rather thought that both these things were wrong manish assumptions.

But I tend to agree with ArcusCalion here, becuase a bit later only we read of healing and increasing of the fëa of Melkor after long ages out of the impotent stage it had been in. And that as long as it could not effect its revenge it would be 'as it were, a dark shadow, brooding on the confines of Arda, and yearning towards it.' Since the windows of Niëna's Halls looked out of Ea to the outer Voide could as well mean both, but How could we explain a sopposed return of Melkor, if Eru had removed him from Eä?

Anyhow we should be more explicit than the text is. It is for our readers to decised what they belive to be the true tale out of these equivalent oppions, not for us to deprive them of the choice!
