Comment 1 for bug 2027838

From the debian changelog, it appears this script was added to perform an automated switch when xen is in use. It was added prior to 2015, and does not appear to have been substantially modified since then. So, I suspect a question may be if this xen use case is still important. If not, then your suggested course of action could make sense.

OTOH, if the automatic behavior with xen is important, then it sounds like what is needed would be either a way to ensure user settings in /etc/libvirt/libvirt.conf take precedence, or to provide administrators with a straightforward way to disable the automated behavior.
