Definitely. Which is why I do want to add some properties to allow users to help guide the type of floppy drive they get. 2.88MB might well be a saner default for when no diskette is inserted (It allows for, I believe, the widest choice of likely types to be inserted later.) Windows (MSDOS through Windows8) and Linux both seem completely fine, which I think represents the lion's share of likely guests. For other guests, you can always tweak the CLI to provide a drive type the guest can use.
