The fact that you used this to debug problems is not relevant to any fix
you might have developed for those problems; the fix can be explained
without needing to know how you got there.  Similarly the debugging is
hopefully useful in general without needing to know which particular
problem prompted it's creation.

This is a bit of a warning sign that the series isn't very focused.
It's also just not good practice, sending patches with obvious problems
(especially obvious problems that aren't clearly flagged up as something
temporary) will frustrate reviewers and can often lead to other issues
being obscured.
