It was fixed a while back, but there are still older versions still
being distributed with some operating systems. For exampel, LTE releases
with 5-10 year support cycles. Being able to use 1 byte limit is a good
sign that your Squid is not affected. The point of the documentation
warning is to make you be careful and check when going small.

It is reasonable to retain the conservatism regardless of this bug and
test your version before changing these limits. The effects of limiting
responses is clearly visible to the end users, even if this bug is fixed
in your Squid.
