Maybe that's true for Debian today, but if there was a blanket rule that this
is always safe on all OS distros, we would not have needed to write this code
in the first place.

And we have done so, but we still have to defend against people running older
versions of libsasl that haven't been corrected.

Though it goes against our usual desire to minimize distro-specific patch
maintenance, I think in this case I have to recommend that you continue to
carry this patch on your side.
