We (DuckDB-Wasm) are also looking closely at OPFS. IMHO the requirement here is not even to get to full ACID. With OPFS, we will get close enough to IndexedDB on steroids and bypassing the js heap limits through out-of-core operators. After all, we are still running in a browser. So I see the value of Wasm-based databases to be a front-facing accelerator, not a substitute for robust storage solutions.
