This is sort-of intentional but I think you raise a interessting usability issue here. The blacklist/whitelist consists of regular expressions but that is actually not super user friendly as its not obvious and they are also hard to use compared to something like glob/fnmatch style matching (or plain packagenames). I can't change this easily without breaking existing setups though. So I think better documenting it is the first step. It could simply use it as a plain string if the regexp fails and display a warning. Or I could add a new Unattended-Upgrade::Package-Blacklist-Plain list for non-regexp content (it really should be the other way around, Unattended-Upgrade::Package-Blacklist-Regex and Unattended-Upgrade::Package-Blacklist would be plain but that is tricky due to the compatibility concerns I outlined earlier.
