I didn't start this, a mod did! I started caving in the 1970s on Stinkies. Nice light, but a PITA, always flaring up or going out. I had to find my way out of a cave with no light in the late 70s, (exploratory trip), cos my Stinkie went out and the flint wouldn't relight it. (And they weren't nicknamed Stinkies for no reason!)
I know, I know, should have had a spare light. Would have been a candle back then though, lol. That's all we had. Luckily I had a friend waiting near the entrance. Just watch the videos by SC Avalon washing soot off flowstone, they are enlightening. I have no more to say on the subject now.
