If you are writing that using dh is more easy than using "normal" debhelper,
then I don't agree, it's not always the case. I've seen many overly
complicated
packages with tons of dh_overwrite_* stuff, which makes the work flow very
complicated and barely readable.

I'm not bying into the legend that a dh using package is more easy to
maintain.

As for the performance, it's quite obvious that dh is doing so many useless
debhelper calls. Just read what you see on screen.

I hope you didn't miss-read me. I do push for using debhelper, but not dh,
which I have reasons to dislike. One of the most obvious reason is that
people
are going to just rely on things they don't understand. It's hiding a
complexity
that people HAVE to understand. CDBS is even worth than dh in this regard.

Exactly!!! And while I'm not pushing you to like or use this type of
packaging,
I don't see why you should push me for another one.
