Not at all. You can use model classes for almost any information
retrieval purpose. I even use it for static (or almost static) data,
maybe just because it feels right to do so. Take a look at the example 
snipplet I've attached below: this is a model that just returns an array
of hash refs that have been blessed into the class itself (similar to
the way Class::DBI retrieves objects, just for consistency).

Another example where Catalyst just steps out of the way when you don't
need it.



package XXX::Model::Publications;

use strict;
use warnings;
use base 'Catalyst::Model';

__PACKAGE__->mk_accessors( qw(pdf_file title topics) );

sub retrieve_all {
  my $class = shift;
  return [ map{ bless( $_, $class ) } (
		pdf_file => 'bg 12 papst 04-05.pdf',
		title => 'Papstbeilage 04/05',
		topics => [
		  'Karneval in Rom',
		  'Das Spiel zum Papst',
