Personally, I think the vaping community should be trying to convince people to always use lipo charging bags. They are cheap and add a fair amount of protection against batteries exploding/venting while on the charger. And the vast majority of the time, when a battery "explodes" it's either on the charger, or it's the very, very first time it was put under load after coming off the charger. (ie, the first time you hit the power button. Which is why some say to hit the button, that first time off the charger, while holding it at arms length.)
But these kinds of things are very, very rare anyway, and I suspect that a lot of the companies don't want to sell lipo charging bags because when you start saying "And you need to buy some safety equipment" you scare the uninformed.
When people tell me "I heard about a battery that exploded" I tell them "Yes, I'm aware. But that can happen to any battery. Your cell phone battery, the one in your laptop, the one in your car. Google for 'Prius battery fire' and you can find an example of a major fire. Any battery can explode, and if you follow basic safety procedure, it's not enough risk to concern yourself".
Probably the biggest change I've made is that I used to use a mod that had stacked batteries, and I'll no longer buy anything that stacks batteries, as it seems to add a fair amount of risk and there are better options.
