I believe the interactions between ucf and debconf were fixed in 2004
(by you)?
Here is a patch against the master branch that adds such a command
called dh_installucf. It also registers the conffiles with ucfr and
removes stray ucf-{new,old,dist} files on purge.

+
+B<dh_installucf> [S<I<debhelper options>>] [B<-n>] [S<i<source destination>
...>]
+
+=head1 DESCRIPTION
+
+B<dh_installucf> is a debhelper program that is responsible for generating the
+F<postinst> and F<postrm> commands that register files with ucf(1) and ucfr(1).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.ucf
+
+List pairs of source and destination files to register with ucf. Each pair
+should be put on its own line, with the source and destination separated by
+whitespace. Both source and destination must be absolute paths.
+
+A dependency on ucf will be generated in B<${misc:Depends}>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify F<postinst>/F<postrm> scripts. Turns this command into a no-op.
+
+=back
+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
