I think the deciding factor is whether future 4.8.z releases will include them (so that we can simply update instead of applying single patches). But unfortunately this seems to be simply not decided yet [1]. If they change it, updating now would be much better because to install the update libxenlight.so, libvirt and core-admin need to be synchronized. Since the mail reads like it's more likely that it will be backported and AFAICS the change to type=pvh is rather small (so not so hard to backport if it not ends in the official release) I lean towards including the backports now. What do you think?
