Can't say much about the Olden Times, but now it's trivial to show that
UFS, in fact, works ok with various sector sizes using gnop.
I've tested it with at least 4 KiB sectors recently, and I think I
remember trying (successfully) 8 KiB sectors a few years ago in a
project, also successfully.
What might or might not work well, I think, is having fragment/block
ratio other then "8".
