The mount command uses /etc/fstab for the default settings, unless
they are overwritten by options on the command line.  So it doesn't
automatically detect the filesystem...unless you put "auto" as the
filesystem type in /etc/fstab.

So as long as /etc/fstab lists iso9660 as the only filesystem for
/cdrom, to mount any other filesystem would require a command line
option.
