I found where it was claimed it doesn't work.  This is the link.

https://askubuntu.com/questions/1007716/formatting-an-ext4-partition-with-a-16kb-block-possible

That is a few years old and things may have changed.  I also saw similar
info elsewhere.  I may try it just to see if I get the same output.  If
it works, fine.  If not, then we know.

Odd it would have the option but not allow you to use it tho.  :/
