Of course, the question is whether all this matters. Is it important to save 8 bytes on each unicode object? Only testing would tell.
Last year, I tried to profile memory usage of web application in my company.

Without -OO option, str is the most memory eater and average size is
about 109bytes.
(Note: SQLAlchemy uses docstring very heavily).
With -OO option, str is the third memory eater, and average size was
about 73bytes.
So I think 8bytes for each string object is not negligible.
But, of course, it's vary according to applications and libraries.
