That breaks existing code in two different ways which I don't think makes it easy.
Correct, it would break existing code. Which is why it should have a different name rather than altering the existing split function.
it does NOT collapse adjacent characters: >>> "a&&b".split("&") ['a', '', 'b']
Also correct. But that is the behavior when splitting on the default white space. ie.. split() with no argument. ' '.split() is not the same as ' '.split(' '). Q: Would it be good to have a new method or function which extends the same behavior of whitespace splitting to other user specified characters? I would find it useful at times.
the separator it splits on is a string, not a character: >>> "a<b><c>d".split("><") ['ad']
Yes, I know. To split on multiple chars in a given argument string it will need to be called something other than .split(). Such as .splitchars(), as in the example equality I gave. longstring.splitchars(string.whitespace) == longstring.split() Note: longstring.split() has no arguments. .split(arg) splits on a string as you stated.

I think string.split(list) probably won't do what people expect either. Here's what I would expect it to do:
>>> '1 (123) 456-7890'.split([' ', '(', ')', '-']) ['1', '', '123', '', '456', '7890']
but what you probably want is:
>>>re.split(r'[ ()-]*', '1 (123) 456-7890') ['1', '123', '456', '7890']
using allows you to do that and avoids ambiguity about what it does.

Without getting into regular expressions, it's easier to just allow adjacent char matches to act as one match so the following is true.
longstring.splitchars(string.whitespace) = longstring.split()
