• Do not install the following configuration files which are not used within the
  Debian package of fail2ban:

  Closes: Debian bug #767123 (https://bugs.debian.org/767123).

I've had thought about this as well, but your example already shows the problem with it (at least the first one that github sent me via mail):
/bin/ls $(DESTDIR)/etc/fail2ban/paths-*.conf | grep -v debian | xargs rm -r
You've missed the common file ;-)

So personally I'm a bit reluctant of removing files per wildcard, which could in the end even cause security issues (things not working correctly, when a file is missing, but nobody noticing it)... so unless you insist, I personally prefer to add new files to the black list as they appear and are not required for Debian!?
