Youch, that's something I bet people haven't thought of. Beneath the collars and wing sheaths there got to problems. And eventually ones that could start killing pegasi and even other mares if there isn't care taken.

Bingo.
I have a pet parakeet, she is 9 years old now, that had a skin condition that occasionally restricted the growth of her flight feathers. Because of the resulting irritation, she began plucking her feathers, and we had to put a plastic cone on her neck to stop her. This, unfortunately, made it impossible for her to preen while we were treating the condition, so during molting, feathers got stuck and we had to groom her ourselves.

It was on this experience that I based the removal of the wing sheaths.

Sorry for the late reply, but... why isn't this something in the Post-FoE forum? It's fun, it's not hateful, everyone can put something in if they like. Sounds perfect, no?

I left that group. Seemed pointless.
