Backup superblock, inode table, space reserved for root, etc.

Test it yourself. Make a filesystem both ways and  do a df and see how
much available space you have.

Not yet. Besides, you have no control over how the disk is formatted. With
superformat you can squeeze more space out of the disk. In other words. If
you had an unformatted disk you would STILL have to run superformat to do
the low level format.

I NEVER EVER EVER trust a floppy that was not freshly low-level formatted.
You can not do this with mke2fs. You will end up with unreliable
diskettes.
