I also opened a bug report for the fusefs case. It is
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200513. It includes a
shutdown script that will unmount the file systems cleanly, though it will
unmount all fusefs file systems, whether they need it or not. Many fusefs
file systems are read-only or fully synchronous, so are always "clean".
But, as far as I can tell, unmounting does not harm for any fusefs file
system. (Yes, "fusefs file system" is probably redundant.)

The shutdown script is only for systems running the native fusefs code and
not the older fusefs-kmod port.
