You'll have to ask the two core devs. In my post, in the part you
deleted, I wrote:
Two senior developers have rejected this feature, saying
that we should just use a lambda instead.
My guess is that they were thinking that there's no need to complicate
itemgetter for this use-case when it is just as easy to write up a quick
lambda to do the job.
For what it's worth, your itemgetter2() is about 1600% slower on my
computer than the real thing. I know I didn't specify speed as a
requirement, but I mention it because on the bug tracker, the importance
of keeping itemgetter fast is stressed.
