I think it's more the case that things may spread if they don't have any disadvantage (like causing death).

This goes against evolution theory.

In evolution theory things that do not have any evolutionary advantage neither spread or die off.

But in practice everything comes at a cost, so generally they will die off.

It cost calories to create feathers, so if not useful they will disappear.
