Because it's untrue for bytearray, and possible object reuse is a general
characteristic of immutability for str and bytes. If another implementation
makes a copy for some reason, it would still be considered "Python".

Since the sentence thus conveys no useful information, I removed it from
both the text and binary variants rather than coming up with appropriate
wording to indicate that the behaviour of returning a new reference to the
existing object when no content changes are needed doesn't apply to the
mutable bytearray.
