Yes, it's one of the applications. I have two uses for it:

 - I am currently using autofs to automount NFS shares from a server,
and I have trouble with permissions, because my user is in more than 15
groups (this is an NFS-specific limitation). So I wanted to replace NFS
by sshfs. I found the afuse filesystem, based on fuse, that provides
automount capability. But it unfortunately lacks automatic unmount on
inactivity.

 - encfs already provides this feature, to unmount an encrypted
filesystem if it isn't used (for security purposes). This avoids having
to remember unmounting it e.g. before leaving my laptop.

Even if I don't use afuse for automounting (due to its overhead), and
instead mount my server using sshfs by hand, I'd like it to unmount
automatically if the mount is idle for a few minutes.

I could have extended afuse to implement the unmount-on-idle feature,
but I figured it might be an interesting feature for other filesystems
based on fuse, and I was able to implement it a bit more elegantly in
the library itself.

Those were my reasons for implementing the feature in the library.
Csaba's positive feedback comforted me in pursuing this solution. But it
remains your decision to include it or not. I am open to discussions
about doing things differently, and to rework the patch if need be.
