Plenty. Suppose you're working on a cross-platform application, building for web will get even easier, as up until a few months ago there weren't even official WASM builds from SQLite (but some amazing community run ones such as sql.js!). As for why somebody would want that, an example: your browser and everyone's is probably always open when you're at a PC, attrition is next to none compared to having to download an application, it's great for even just trying something out. SQLite really makes user data storage trivial in most circumstances, key:value doesn't.
