We certainly don't need '&&' and '||' -- we already have them, they're called 'and' and 'or'.

But if booleans are to become a separate type eventually, I think that '&' and '|' should perform the standard (non-shortcircuiting) boolean algebra operations on them.

In fact, that could be added now to the reference implementation in the PEP -- I don't think it would introduce any extra breakage.
