I'm going to argue that some duplicates are going to be expected when you
have patterns like **/a/** that can match the same directory name using
two different "paths," if you will. Other shells that implement **, such
as ksh93, agree. Imperfect, but there's not a good solution.

Interesting. So it is up to script writer to delete duplicates. Will you
be interested in patch which will clear duplicates? Let's say it will be
some function run after expansion. And it will be optionally turned on.
I guess it will not have any higher glob execution time impact.
