  `kio-fuse` was designed with this in mind and does not even support unmounting. When the file isn't being used anymore, it drops everything except what's needed to reopen the file when requested.

  In this case it would be as easy as just calling `org.kde.KIOFuse org.kde.KIOFuse.VFS mountUrl` with the url and it gets a local path back.
  
  This should ideally be handled transparently by the KDE file dialog though.
