Yes, the mandatory picnic was part of the third prophecy of Mandos.

Anyway, rather like the alternative version of orkish origins being that orc bodies were inhabited by Maiar, but then somehow devolved into mortality, there is often an ambiguity or possible alternative. The entwives, however, are more an enigmatic mystery rather than ambiguity. And one I don't think Tolkien ever wanted solved. Mysteries along that line obviously amused him.
