Aren't you patching all the programs on the system weekly using the built-in tool? Using dpkg directly is not needed.

Using dpkg directly when there are other dependencies involved is not safe unless you are an expert. I only use it directly for programs outside any PPA - perhaps 2 across all the machines that I manage.
OTOH, if you're already doing this, then it is time to get the newer dpkg source code and start compiling yourself.
