If you say it's safe for you then I'll take your word for it. I wasn't there, I don't really know. Just sounded a little on the edge... but I get it.
We broke through the ice last weekend in a quarry to get one in, so I'm not one to judge at all... some would say that's also Russian Roulette, but I know the quarry, I know the underwater landscape, I made sure we could break through if we came up. It was fine, redundant doubles drysuit and all that.
I also lost a fin when getting out once. Thankfully I had a buddy with me that time and he was ok doing a little muck diving to find it. Same damn quarry, lol.
