Well, there's a caveat there - openQA doesn't test everything. On the
whole we cover quite a lot with the set of tests that gets run on
updates, but there's certainly lots of potential for there to be
important bugs it misses, that a human tester might catch. So I think
there is still a case for the higher karma requirements too.

On the whole, though, I agree with you. I just don't trust my own
opinion because it's obviously biased by what's convenient for me. :D

I actually did a huge rewrite of the thing that generates the critpath
data this week, and it probably wouldn't be tooooo much work, honestly.
The most annoying bit would be the Bodhi frontend stuff, but that's
because I'm bad at frontend dev in general. :P But yeah, this is
definitely off in sky-castle land. I'll add it to my ever-growing list
of sky-castle projects to do when I get a couple of years of spare
