Correct.

The group permissions assigned by udev are for *daemons* only, they are
*not* for users to be put into. To quote from the udev documentation:
In general, "normal" users who log into a machine should
never be a member of any such group, but the device-access
should be managed by dynamic ACLs, which get added and
removed for the specific users on login/logout and session
activity/inactivity. These groups are only provided for custom
setups, and mainly system services, to allow proper privilege
separation.

Real floppy devices only (ie. /dev/fd0 and its compatriate pieces)
because formatting those needs special handling.

That was a bug, they should always have been in "disk".
