I guess if I was in an emergency, and there was no other way to reseat the bead, I might consider the explosive techniques.
I have been an eye doctor for 35 years, and I have see lots of trauma to the head and neck over the years. That is why I am conservative about things that explode. If something goes wrong, it can go wrong big time.
I can say that I personally don't know anyone who has been hurt using the ether explosion technique. I am wondering if anyone out there knows of anyone harmed by using ether to reseat beads.
