Right now it's non-trivial to extract the QA warning entries from the log; maybe we should have some kind of ewarnqa to export only the QA-related warnings? I know it's not trivial, but still if somebody has an idea...
I'd like the output of the QA with the package-name so a simple grep 'QA-' perhaps of the logs could then be filtered to a file which I could then run through more strenuous checks. cat /var/log/portage/* | grep QA- if the QA string with package name is just slightly different from the default string? Or anything you could think of that was faster.
You might save dev time by not leaving bug-wranglers without a buildlog and emerge --info notify users on bugs.gentoo.org of the change as instituted when it happens so they know up front. If this info is necessary to make the most of the dev/maintainer then it should be provided when they get the email notice. They shouldn't have to ask for it. After a number of hours if not provided bug-wrangler should change to needinfo automatically if requirements not met. Perhaps the output of the notices could be colored to indicate severity level
