The problem is that most people's phones aren't actually bricked. If you decide to root, you should know how important it is to use SPRecovery and have a Nandroid backup. If you go through the proper steps, it should be pretty damn hard to actually brick the phone.
Several post similar to this one, I think we understand that in the truest sense of the word the phones aren't actually bricked. No more then when people would brick there Blackberry Storms. Heck I did that to mine a few times but that was the term we used when something went wrong and we got stuck and that's what I'm basing this particular thread about.
My point again is that to avoid having issues that you may or may not recover from before you decide to root just make sure you understand the directions first. If you don't then it's probably best to avoid it. Up until rooting started it was never even seen in the forum before. So irregardless of whether or not the phone is actually bricked or not, people are indeed having issues and should be prepared as you said in your post by knowing exactly what to do.
