I think the idea that God can't produce a proper creation the first time, that he's a screw-up and doesn't plan ahead, and he had to "fix" his creation to make it work right is blasphemy.
I use the term Limiting or Diminishing, but as I said, it is the only eay for small minds to wrap themselves around the idea of true Omnicience. Most people, particularly religious people, want and need a God made in their image -- Gandalf the Wizard writ large. The idea of a God that is outside space and time and figured ot all out up front is too overwhelming for them.
Thus, they reduce Him accordingly.
