It does get rid of the default drive.

As soon as you use -device floppy, the default drive goes away, too, so
you don't have to use a secondary floppy drive. It's like the default
CD-ROM that goes away if you use -device ide-cd.

So if you want to give it an ID, the solution is as simple as:

    -device floppy,id=foo
