Yep, the phrasing in the man-page is not clear.  In the past it has
confused me as well.

I do not see how they add "unnecessary directory structures", the point
of hashing is to avoid very large [fat] directories by making the tree
deeper and more narrow verses fat and shallow.  In some cases [albeit in
large part historic] this improves performance due to technicalities of
file-system operation.

I would recommend just keeping the hashes if that is what you have now.
There no significant benefit to eliminating them.
