parse-defsystem.lisp is probably the remaining part of asdf that
received the least love since the days of ASDF 1. There were code
cleanups and bug fixes, but the structure of the code and its rigidity
are about the same.
If you have proposals on how to make the code extensible, e.g. in the
style of resolve-dependency-combination (or as macros that expand to
such), then you are most welcome. The test suite will help you make
sure you aren't breaking anything — please add to it to make sure
noone will break your code.
