There has been a lot of pressure from various developers to remove old software.
I mean, in theory p5.8-foo would probably still compile and work just
fine, but it causes extreme headaches and days of delay on the
buildbot. Plus problems when upgrading ports that would be stuck with
OK, so we moved all the old perl and python modules ports to
graveyard. But now we are getting requests to add some of them back.
(In order to have older versions of Python working some of the modules
indeed make sense.) And again pressure to remove that software as
well. Perl5.8 wasn't broken and people requested to add perl5.14 back,
perl5.16 up to 5.24 works just fine from what I know. I cannot decide
whether to keep it or to remove it. I don't have a problem maintaining
two extra versions and they don't hurt anyone. But there's constant
pressure to remove those. Putting them "aside" and making it easy to
add them back (while requesting a bit of extra steps from users) might
satisfy both groups.
I know that on Debian I can probably pick between two versions of gcc
or python, but certainly not more unless I make some special effort
and perform some additional steps to be able to do so.

There are certain groups of ports that are simply there for no good
reason. They might have worked 10 years ago, but no longer even
compile. I'm always afraid to delete them though because that takes
quite some research and you never know whether a port is useful to
some people or not. If we had a special group, I would take the task
more "lightheartedly" and just move those ports aside. And if nobody
complains for a long while, potentially remove them. Many ports also
give false impression that they are supported. Users try to install
it, it fails, there's no maintainer, nobody willing to take a look at
the ticket ... people might just as well leave MacPorts because of
frustration. A special category would at least make it clear "here you
have the port, we know it's broken and there was nobody around to fix
it, but if you want to use it and if you are willing to take some
effort to fix it yourself, you can start where others left".
As for why the buildbot would not build old Pythons and Perls, I have
no clue. In fact I'm mixing a lot of different categories of ports
together and all the rules don't make sense for everything that I put
into the mixture.
But not having broken ports in index would certainly avoid confusion
for users. As a newbie I would be way more frustrated to see the build
break (and not see any progress at all) than not to see my favourite
software listed at all.
I don't like the fact that we have so many different kinds of failures
and we find it difficult to find the most critical ones ourselves.
> What would the instructions that you suggest to point the user at say?
A clear message that says something in the following sense (not
literally of course and a bit depending on the reason why the port
ended up there in the first place): "Look, this is some software that
you can use at your own risk; you need to do at least this and that to
confirm that you really want to use that older software and so that
you confirm that you know you might be on your own. If it works for
you, fine, we are glad that we could help you. But if it fails, either
send us a patch, or don't complain too loud (we don't want to keep a
ticket open for another 10 years that nobody is interested in fixing).
If you believe that the port ended up here by accident and that it
should get full support again – if it works and you find it super
useful, feel free to tell us that. If it's broken and you know how to
fix it, we might also consider adding it back."

A policy that says "maintainer is the boss and gets to decide when to
retire old ports" is still better than no policy at all.
At the moment I constantly find myself in the middle of flame wars of
whether or not to keep supporting old software like perl. I would
prefer "a greater authority" to help me decide when to cease support,
so that I know which ticket to close as "wontfix" - the one requesting
removal or the one requesting adding the ports back :) :) :)
But independent of old perl/python/clang/gcc/apache/php/... policy, I
would again like to stress that I would want to have some special
department for old and most likely useless ports. Like software that
depends on wxWidgets 2.8 and will never get ported to 3.0 (with
potentially zero users).
