I think a large benefit to "DB in browser" is about the whole "local-first" software movement. A good overview is written here https://sqlsync.dev/posts/stop-building-databases/

The essence of the approach is that a large majority of FE apps have constructed quite complex caching layers to improve performance over "querying backend data" - take a look at things like Next.js or React Query <- as the post above mentions, they're essentially rebuilding databases. So instead this approach just moves the db to the browser, along with a powerful syncing layer.

I think it's an approach that deserves more attention, especially to improve DX where we end up writing a whole lot of database-related logic on clients. Mind as well then just use a database on the client as well
