Better comparison is to see how much space is used by one copy of it,
and how much by two copies:
>>> sys.getsizeof('aa')-sys.getsizeof('a')
1
>>> sys.getsizeof('ẞẞ')-sys.getsizeof('ẞ')
2
String objects have overhead. Big deal.

Clearly. And similarly, the 16-bit integer has been completely
obsoleted, as there is no reason anyone should ever bother to use it.
Same with the float type - everyone uses double or better these days,
right?

Nope, nobody uses small integers any more, they're clearly completely obsolete.
