They **don't** have basically the same signature, though.  max() takes 
either an iterable or two or more numbers.  Using max(*list_) presents 
it with a series of numbers, so that's OK.

sum() takes just one iterable (plus an optional start index).  Using 
sum(*list_) presents it with a series of numbers, and that does not 
match its signature.

Check what I said:

 >>> help(sum)
Help on built-in function sum in module builtins:

sum(iterable, /, start=0)
     Return the sum of a 'start' value (default: 0) plus an iterable of 
numbers

 >>> help(max)
Help on built-in function max in module builtins:

max(...)
     max(iterable, *[, default=obj, key=func]) -> value
     max(arg1, arg2, *args, *[, key=func]) -> value

Why they have different signatures may be lost to the whims of history 
and backwards compatibility...
