If the software is mature, there usually aren't that many changes to the
manual page.

And I wonder how many people are actually using NFS these days. In offices,
SMB/CIFS seems paramount these days.

From the amd(8) manual:

    File systems are automatically unmounted when they appear to be quiescent.

It seems you and amd have a difference of opinion about what active/quiescent
means...

The `cache_duration` parameter is the one you're looking for, I think.
After entries are dropped from the cache due to inactivity, amd tries to
unmount them. See also `dismount_interval`.
