Only if the energy density is not important for your application. There are such applications, but they are a minority. Smartphones, laptops, car batteries all want to be both light and small.
The same argument could be made for nickel-iron batteries, though. They're heavy and bulky, but they last literally forever, and their source materials are ludicrously abundant. Why don't we see nickel-iron grid-scale storage? I'd love to know.
Their primary use is in applications where their long lifetimes outweigh all other considerations.
