But I think the logical consequence of your approach would be that sum([]) should raise an exception rather than return 0, which would be backwards incompatible. Because if the identity element has a default value, the default value should be used exactly as if it were specified explicitly.
In that case I would argue in favour of keeping it the way it is, since...
currently sum([1,1], 40) equals 42.
...seems quite reasonable to me. Or at least as reasonable as anything else.
