As long as they don't let WebAssembly have raw access to the host filesystem, they'll do well. "No access" is the best access choice for the default.
As adoption ramps up, the pressure to make filesystem access "easier" will increase. I just hope they hold it off, as isolation is the key feature of the platform.
