(Well, ok, given the current release structure having an update today

theory a patch release could be made on the last day of support for a
branch.)
A simple solution would be for there to ALWAYS be a patch release on the
last day of support for a branch, that creates /etc/NOT-SUPPORTED or
similar. Then it's just a matter of adding an /etc/cron.daily job to
report on that, as long as you are following updates (and if you aren't
you don't care about this issue).
I can't think of any other OS that does this, either - they generally
just report that there are no available updates.
You can do a lot of nice stuff just parsing the cvsweb. For example,
here's a very basic script for showing supported branches:
#!/usr/bin/perl -w
use strict;
use LWP::Simple;
print Supported branches of FreeBSD:\n\n;
my @content = split /\n/,
get(http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/www/en/security/security.sgml;);
die Couldn't get url! unless @content;
my $line = shift @content;
do { $line = shift @content; } until ($line =~ /name=supported-branches/);
do { $line = shift @content; } until ($line =~ /table class=tblbasic/);
while ($line = shift @content) {
last if $line =~ /\\/table\/;
if ($line =~ /\t[hd]\/) {
$line =~ s/[^]*//g;
$line =~ s/^\s*//;
printf %-20s, $line;
}
print \n if $line =~ /\\/tr\/;
}
