A nice point, but really, you lose a lot by doing so. Even simple things
like the ability to write:
if word == 'X'
instead you have to write things like:
if word[0:1] = b'X'
if chr(word) == 'X'
if word == ord('X')
if word == 0x58
(pick the one that annoys you the least). And while bytes objects
do have a surprising (to me) number of string-ish methods, like
upper(), there are a few missing, like format() and isnumeric(). So it's
not quite as straightforward as "done". If it were, we wouldn't need
text strings :-)
