: 
:     Because the defacto floppy size was increased from 1.2MB to
: 1.44MB, or because floppies should die (pc98 folks would probably
: disagree though as that's why sysinstall still has floppy support :/)?

No.  Because the size sysinstall has to fit in is now constrained by
the CDROM's size, not by the floppy's size.
