Sergey, please stop calling the current documented behavior a bug. https://docs.python.org/3/library/functions.html#sum says 'The iterable‘s items are normally numbers ... To concatenate a series of iterables, consider using itertools.chain().

To make a change, there must be discussion and approval on python-ideas, including by Guido.  I believe that GvR's rejection of optimizing for strings covers optimizing for other sequences.  If you want to continue, make a pep-like post there that summarizes the discussion here and makes your current proposal.
