I think they're caught between a rock and a hard place here; section
3.7 of the FHS you quote above describes /mnt as "Mount point for
mounting a filesystem temporarily".  My reading of that is that
temporary mounts are to be made directly on /mnt, leaving no option to
create /mnt/cdrom, /mnt/floppy and so on.  I guess rather than screw
up something that has expected behaviour, they decided to add
something that has no expected behaviour.  There may have also been
precedent in previous Debian releases; I'm only familiar with potato.

FHS 2.2-beta reiterates that /mnt is a mount-point and adds provision
for a /media directory, which is to contains mount-points for
removable media: /media/cdrom, /mdeia/dvd and so on.
