Which wouldn't protect the lens against bangs in daily use,
which is the other important reason for lens hoods. But
then, it's probably the price to pay for flattening them.

If the lens hood is in place and an object like a stone or pebble "kicks
up", it's less likely that it would hit the front element than if the lens
hood is not on.

I don;t really understand how a lens hood protects the lens.
I've always found it make it worse because the 'lens' is actually
longer
with a lens hood attached and therefore more likily that I or
something else will
knock into it.

Take a 70-200mm lens with a chopped tulip style lenshood. I.e. a
rather long one.

Unless there's something rather long and thin, it'll be stuck
in the lens hood before reaching the front element. Same for
fingers --- you have to actively reach inside, there's little
chance you'll touch the front element by accident.
