from https://www.debian.org/doc/debian-policy/ch-opersys.html section 9.3.2

"The /etc/init.d scripts must be treated as configuration files, either (if 
they are present in the package, that is, in the .deb file) by marking them 
as conffiles, or,...."
"...Only when dpkg is executed with the --purge option will configuration 
files be removed. In particular, as the /etc/init.d/package script itself 
is usually a conffile, it will remain on the system if the package is 
removed but not purged. "

so the behaviour is expected ... that the generator kicks in in this case 
smells like a bug though, it might need to check if the related package 
actually exists on the system...
