But your objection would also be handled with a special-case function
which only took an int/long and a base and returned the string
representation for that base, no?  This could be a method or a class
method of int, or a new function in math.  What makes it special enough
to warrant being part of the string constructor?

There is a symmetry for str(float(s)) == s and str(complex(s)) == s.
Why shouldn't those take a base?

Well, almost symmetry.  str(float("1.1")) != "1.1"
