The design for dpkg is the implementation of dpkg. This makes it
hard to change. Take a look at the bug-tracking system for some
Dpkg's implementation is:
(*) A database implementation
(*) A system administration application
(*) A complex command-line parser
(*) A complex state machine
(*) A package manipulation tool.
If these were implemented as separate pieces of software, that would
be one thing, but it's all wrapped together in a fashion that requires
intimate understanding of the whole before making any changes. And,
of course, any mistakes could damage the integrity of someone's system.
[Aside: the package manipulation tool is a separate piece of software.]

Possibly. But that's not a trivial task. Just analyzing the current
system to extract a reasonable design is a daunting task. [Then again,

The apt folks have come up with some very clear documentation on some
aspects of dpkg. But they don't address the tangle of functionality
and implementation techniques represented in the current system.
