The only people who have to ponder this question are those who are completely reckless in rooting their devices. Those who don't think twice about rooting, or jailbreakers if you will, would laugh them right out of the building.

Even if someone were to mess up the root, they could return their device back to factory condition rendering a return unnecessary. Even if they did return it, if it's returned to the original state in which it was bought, why would it be a problem? I say let people do whatever the heck they want with the stuff they own outright. Those who decide to alter their devices likely have accessed the risk and go into it prepared. Luckily, rooting is far kinder to hardware than physically taking it apart and then putting it back together.

I will never understand why rooting concerns the finger-waggers anyways. If you think rooting is unethical or too risky, don't root. Simple stuff. Be happy and enjoy the stock firmware. You worry about your device, I'll worry about mine.
