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.
