urlparse converting bytes to 'str' to operate on them is at best a kludge - you're forcing 5 times the storage (the original bytes + 4 bytes-per-byte when its decoded into unicode)
That is itself an implementation detail of current Python, though, due to it only having one internal representation of unicode.
In principle there could be a form of str that keeps its data encoded in latin1, in which case constructing it from a byte string could simply involve storing a pointer to the original bytes data.
