[Supernatural] All the angels who were cast from Heaven lost their wings in the fall. What about the angels on Earth at the time? Do they keep their wings?

We know the ones that fell still have grace, so the ones on the ground obviously shouldn't have been affected by the fall, and certainly less so in losing their wings.

The fall was more than a literal fall (although most did literally fall), it was about being cut off from all the power of heaven.

Falling from heaven/the sky, couldn't actually hurt an angel but being cut off from heaven can do some serious spiritual damage (as shown) to an angel.

If angels had kept their wings from being on Earth then they would have been irreplacably valuable and would have been showcased by either side at some point.
