Is OPFS backend supported? how to use it?

[ali4864]

In Filesystem-API there is not any information about origin private file system (OPFS) but we have wasmfs_create_opfs_backend(), what is the standard way to mount a persistence path using OPFS? Is it an experimental feature?

I believe the backend is fully functional and used in production. @tlively would know best, and about the status of documentation for it.

Yes, it is production-ready. There unfortunately are not great docs for it, but you can see how to create and mount the backend in the tests.
