Do Riding Horses Survive Battle?

How, Riding Horses aren't ridden into battle.  I believe that was the reasons the devs stated for why they offered no attack or defense bonus.

That logic would explain why it balances out with Heavy Warhorse for wolf riders, but not Riding Horses for swordsmen, trueshots, etc...

I'm not demanding anything.  I'm asking how it works.  We assume these crafted things will be destroyed when the troops are destroyed because that's how the cheap stuff works.  But they are making changes to the combat model.  When we attack animals they drop stuff, so it's clear that we have a new possibility in combat now.  I'm a little curious if they plan to extend that to troops or not and if so what sort of things that may imply?  I'm definitely not demanding anything though.
