Yeah, we're well aware of OPFS, and perhaps in the long term future it will be the best way to persist data in a browser.

Although we're super impressed with all of the active research and work going on in this realm, we're trying to build a bulletproof product and therefore need "boring and stable", not "new and shiny". Trying to save ourselves serious headaches.

We're keeping a close eye on Zero.

Also, almost all of these projects are relatively storage-agnostic. So it should be trivial to write adapters for OPFS, or indeed FS in iOS/Android contexts, etc. Most can work with any get/set API.
