This sounds like unattended-upgrades should just add this to its blacklist by default and only notify about it but leave it to the admin to actually perform the upgrade of this package. OTOH however this would mean that when people explictely use "really_stop = true" it would still not get upgraded. If that is really really rare, then I think the tradeoff is sensible and its better to blacklist then to fail.
