not quite, at leat from a practical POV:
If I run make -f debian/clean, I want the package to be in a state to build 
again when runing make -f debian/rules binary. And I don't want the .diff.gz 
list any remains of failed attempts to modfify the package.

from that practial POV I'm not really interested in if a package decides to 
remove files on clean that can/will be recreated during build, e.g. 
Makefile(s) create from Makefile.am(s).
