(Note, I've numbered your bullets above to respond to them individually)
#1 - if we don't have testers familiar with the packages, and it's a
popular package (either in terms of # of installed systems, interest or
critpath), we (includes maintainers) should be looking to create/develop
testing interest, right? Or, if no engaged testers were found ... do we
1. Wait X days for exploratory test results
2. Or push immediately
#2 - I'd take this case-by-case ... it depends on what is "automated".
Certainly, I could see a scenario where %check includes the upstream
unittest, and the automated package update acceptance plan passes ...
the update is in good shape and ready for additional functional tests
('updates-testing') or stable.
TODO - draft an autoqa test that confirms whether %check ran during
build-time, and ensures it passed.
#3 - Seems similar to #1 to me. Testing is *always* a delay. In a way,
that's by design. That's not to say we as testers intentionally want to
slow a process down to a crawl. So if there are unnecessary delays
unrelated to the act of testing ... let's work those. It sounds like
the delay here is similar to #1, in that testers aren't providing
feedback on security updates?
TODO - draft general security update test procedure

Note though that the %check needs to also pass. I've seen plenty of
builds that include a %check, but don't fail if the %check fails. There
is an AutoQA test in the making here, anyone interested in helping?

No, but I think we would want to at least ensure they pass. I don't
think it would be horrible to pull together an AutoQA test that checks
for the presence of a %check and whether it passed.

I don't object to this. We have experience using shared test systems
internally at Red Hat for many years. There are a lot of system state
issues we'd need to work through, but there are certainly benefits to
having public test systems.
I'm inclined to think the more immediate problem though is the lack of
test instructions, not the lack of hardware. Additionally, over time
the lack of hardware will be less of an issue right (e.g. virt)? But
again, no major objections to shared test hardware, other than it does
involve some setup/maint, and doesn't address the lack of test

Ah, good point.

Good thinking. Is this something we can get on the bodhi roadmap
(https://fedorahosted.org/bodhi/roadmap)? I think Luke monitors this
list, perhaps he'll jump in.

Eeew, it certainly would be! I was more just adding some extra flavor
on the karma "by proxy" practice.

I see what you mean.
