Title:
  New perl dependency in UCF increases minimal image by >10%

Status in ucf package in Ubuntu:
  New

Bug description:
  As far as I found the changelog https://launchpad.net/ubuntu/+source/ucf/3.0044 this might be required as all I can find there is:
        - add missing Depends: procps, ${perl:Depends}

  So if there is a real dependency it can't just be dropped.
  But maybe whatever depends on it can be isolated and separated?

  Because as-is what I see is that minimal images change from

  Old:

  root at o-min:~# dpkg -l | grep perl
  ii  liblocale-gettext-perl            1.07-7                            amd64        module using libc functions for internationalization in Perl
  ii  perl-base                         5.38.2-5                          amd64        minimal Perl system

  New

  root at p-min:~# dpkg -l | grep perl
  ii  liblocale-gettext-perl            1.07-7build1                      amd64        module using libc functions for internationalization in Perl
  ii  libperl5.40:amd64                 5.40.0-8                          amd64        shared Perl library
  ii  perl                              5.40.0-8                          amd64        Larry Wall's Practical Extraction and Report Language
  ii  perl-base                         5.40.0-8                          amd64        minimal Perl system
  ii  perl-modules-5.40                 5.40.0-8                          all          Core Perl modules

  And due to that gain extra content due to perl being installed.
  Biggest chunks I've found are:
  - /usr/lib/x86_64-linux-gnu/perl with 26 mb
  - /usr/share/perl/5.40.0 with 23 mb

  
  Nothing changed other than the former missing dependency.
  In particular I see one binary in old and nw:

  file $(dpkg -L ucf | xargs) | grep -i perl
  /usr/bin/ucfq:                                                          Perl script text executable

  But afaics in a trivial test this works fine in Oracular which only
  has

  ii  perl-base                         5.38.2-5
  amd64        minimal Perl system

  
  root at o-min:~# ucfq /usr/bin/file
  Configuration file                            Package             Exists Changed
  /usr/bin/file                                                     Yes
  root at o-min:~# ucfq --help
  Usage: ucfq [options]
  Author: Manoj Srivastava <srivasta at debian.org>
    where options are:
   --help                This message.
   --debug               Turn on debugging mode.
   --verbose             Make the script more verbose.
   --with-colons         A compact, machine readable version of the output.
   --state-dir </path/>  Set the state directory to /path/ instead of the
                         default /var/lib/ucf.

  
  Could we maybe make it depend on | perl-base or any such?
