Thanks for not providing even a single example... I tried looking around and only found relatively niche use cases, like them being more reliable and resistant (while also being lighter) for extreme environments or infrequent use, for example emergency equipment. And then some people choosing em because they don't feel like investing more into it, when they have only a couple devices that drain the batteries slowly, let's say a clock that lasts a year. That could be easily fixed if you could exchange empty batteries for full ones like with gass tanks and similar, and the prior examples aren't a good enough reason to have such batteries in the convenience store.
