Sure but not all backend operations can always be mapped to flat files on Dropbox, like when you have certain real-time collaboration features, syncing on graph/tree-like data structures, or perhaps permissions in case of a company tool. That's why longevity of the "data" aspect is usually easy to solve when a copy of the data is already local, but then you still risk losing a part of what it is that makes the app when there is no way to run the app's syncing backend yourself.

It serves more use cases than you might think, especially with CRDTs. Nestful is a tree structure and uses Yjs for sync. Permissions can be done in the file system level.

Yes, I agree this is not an end-all be all solution, but the tradeoff is often worth it.

Yep love CRDTs but I think we are in agreement that it's a matter of trade-offs whether or not to use a backend (beyond a shared fs service). The idea with ejectable is that if you've decided the trade-off of a backend is worth it to enable certain features/UX, then it's a good way to ensure longevity of the entire app for users.
