It might be nice to have a dh_alternatives scripts to automatically write
any wanted update-alternatives commands for the postinst/prerm scripts
by debian/alternatives or debian/<package>.alternatives, like follows:
(I don't have good idea about debian/alternatives format...)

#!/usr/bin/perl -w

BEGIN { push @INC, "debian", "/usr/share/debhelper" }
use Dh_Lib;
init();

foreach $PACKAGE (@{$dh{DOPACKAGES}}) {
	$TMP=tmpdir($PACKAGE);
	$alternatives=pkgfile($PACKAGE,"alternatives");
	
	if ($alternatives ne '') {
		if (! $dh{NOSCRIPTS}) {
			open(IN, "<$alternatives") || die "$alternatives: $!";
			while (<IN>) {
			    # read alternatives file
			    # and check it
			    autoscript($PACKAGE,"postinst",
				       "postinst-alternatives",
				       "s:#ALTINSTALLARGS#:$altinstargs:");
			    autoscript($PACKAGE,"postrm",
				       "postrm-alternatives",
					"s:#ALTRMARGS#:$altrmargs:")
			}
		}
	}
}

/usr/lib/debhelper/autoscripts/postinst-alternatives:

 if [ "$1" = "configure" ]; then
	update-alternatives #ALTINSTALLARGS#
 fi

/usr/lib/debhelper/autoscripts/prerm-alternatives:

 if [ "$1" != "upgrade" ]; then
	update-alternatives #ALTRMARGS#
 fi
