The problem years ago wasn't the cans, it was operator error, allowable by the design.
With some stoves it was possible to leave the pot support in "transport" mode and use the stove, causing the heat to build up, overheating the gas canister. It would then fail and explode. It didn't help if a large pot/pan was used that sat over the gas can also.
The new ones have fixed pot supports, and an extra level of gas shut off in case of overheat/over pressure. Looks like a major gas leak doesn't trigger any of these safety measures!
Glad it all worked out well for you.
