maybe because join is and has always been documented to take an
unlimited list of items?
join(path1[, path2[, ...]])
Joins one or more path components intelligently. If any
component is an absolute path, all previous components
are thrown away, and joining continues.

if you called "append" with more than one argument, it converted
the arguments to a tuple and appended that tuple to the list
(not at all what "os.path.join" does, in other words). This wasn't
documented, and wasn't intended either -- the reason was that
"append" used an outdated internal API that didn't differ between
a single tuple and multiple arguments. For some more info, see
chapter 10 of this document:
(also see the style guide for more info on foolish consistencies ;-)
