This is also a good "first step" for creating lintian test. For example,
OCaml team know quite well its programming language (OCaml) and the
problem that comes with. We know how to do QA and what tools we need.
Doing a quick prototype with the tool we have (e.g. ocamlobjinfo) is a
way to create a coherent set of test which are perfect to fit OCaml
needs. Once everything is done and running for a time, we can think to
migrate this test by not replacing specific tools (like ocamlobjinfo).
The point is that using external tools breaks reproductibility but helps
to design the test we want (e.g. quick and dirty at the beginning and
then refine).

This kind of "external plugin" architecture can be a very good way for
packaging team to enhance their policy and their QA.
