FWIW, the goal of this field was to help project planning (both going forwards,
and in looking at how we've fared to help project going forwards) more than
contributor assignment. There wasn't any expectation that the correct

+1 as well.
One thing to note, many times when i create a ticket i don't know the
complexity as I just found a bug (most of the time in a system i do not
know); so i tend to default to w/e is in the middle. Leaving the field for
someone else to classify feels iffy as we need then someone triaging
