In what sense unnecessary? Do your floppy drives not
support those modes? There are tools which use the
name of the device to select their mode of operation,
and if you don't have a /dev node for that then they
don't operate properly or even refuse to operate.

I can't recall in which tools I've encountered that
off the top of my head, but I have encountered some
which don't respond to what setfdprm does.
