It's not in a poor state. I will agree we should document how to get
an account on a ppc64 box on the wiki somewhere though.

Where are the test machines for x86_64 documented at? I don't have one
of those and there are no publicly available test machines that I know
of. I guess x86_64 should be dropped to.

That depends on your definition of "primary package maintainer". We
have several in Fedora who are excellent at packaging, and weak in the
areas of programming.

Yes, upstream should always be involved in these cases. That has
little bearing on this conversation.

Why? The arch team is the one with the interest, skills, and
machines. They should certainly be able to work with others to come to
resolution, even if they can't fix it on their own. And if they can't
do it and the primary package maintainer doesn't feel like fixing it,
then an ExcludeArch is added and life goes on.
As for some examples, David has fixed a large amount of issues
despite the fact that he isn't the primary package maintainer. He even
has OCaml almost working on ppc64 for some really odd reason. Spot
has done Aurora Linux for a while now and is working on making Sparc
the first true secondary arch. He certainly doesn't maintain all of
the packages in Fedora. There are also s390, ia64, and ARM efforts
under way. So I'm very skeptical of your "doomed to failure".

You keep saying that, yet you're completely ignoring the fact that this
is not specific to any particular machine type. Fedora, as a project,
does not have publicly available test machines. We never have.
Community members do, and they offer them up regularly.
Even with the help of the community, you can't always allow
$random_maintainer to test particular types of packages on a publicly
available machine that's intended to be used by multiple people.
That's why you have the arch team and volunteers.
If you don't want to be part of all that, then that's OK. If you do,
great. But please don't condemn the efforts of those making secondary
