All reports of maintainer-script-should-not-use-dpkg-maintscript-helper for the archive. The extended description of this tag is:
The maintainer script seems to make manual calls to the dpkg-maintscript-helper(1) utility.
Please use package.maintscript files instead; the dh_installdeb(1) tool will do some basic validation of some of the commands listed in this file to catch common mistakes.
Refer to the dpkg-maintscript-helper(1) manual page and the dh_installdeb(1) manual page for details.
