Currently typing a path into the navigation bar recognizes if it could be a remote path. My feature suggestion is extend that capability to the command line tool as well. When running nautlus <path>, perform a check to see of <path> is possibly a remote resource or not. If this would beak backwards compatability or cause a speed issue for existing programs, then add a flag so the user can specify if they want to enable this automatd check or not.
I don’t think this is a bug. Handling the case where a given path could be a non-local FUSE mounted filesystem seems more like a feature to me. I see no reason why invoking nautilus from the CLI versus pasting a path into the navigation bar would have to use the same codepath or have the same feature set. However, it would be nice if they did, which is why I posed this as a feature request.
That being said, if the maintainers want to consider this a bug, I’m more than happy to work with them from that perspective. Either way I think the implementation will be the same: add a the same remote check that is performed when using the navigation bar when nautilius is invoked from the command line.
