I don't feel Padraig's reply was offensive at all.  Instead, he just
asked for further clarification about the requested feature.
Adding a clear example maybe would have helped.

The default list of file systems includes all but dummy filesystems which
do not occupy a backing store like e.g. the /proc or the /sys filesystems.

Therefore, if someone would like to have a certain type additionally
to that default list - which would obviously be such a dummy filesystem,
then this would be quite a strange corner case IMO.

As you mentioned ZFS in your original email, doesn't GNU df show that
per default?  That would be a bug.

Sound like -type.

Have a nice day,
