dh calls dh_pysupport (if it's installed in the build environment).

postinst/prerm scripts take care of byte-compilation. This is a 
significant difference.

>Depends: [-python (<< 2.8), python (>= 2.7), python-support (>=
>0.90.0),-] libc6 (>= 2.2.5), libncursesw5 (>= 5.6+20070908),
>python-chardet, [-python-feedparser-] {+python-feedparser, python (>=
>2.6) | python-multiprocessing+}

Missing dependencies would be a serious bug.
