Nostalgia; inertia; laziness; perverseness; whimsy; Luddism.

Yes:  string methods didn't exist before Python 1.6.  The string module has
always been there.

Python 1.6 was released in 2000.  Whether that's quite recent depends on
whether you reckon in, say, geological time or computer time <wink>.

If you like investigating this kind of thing, see Misc/HISTORY and Misc/NEWS
in your Python distribution (the latter gets prepended to the former as the
centuries fly by).
