No, I'm saying that given limited resources, addressing the giant piles of
unused code we have (and figuring out how new code won't end up in the
attic) seems like a higher priority. Using better tools is always a good
idea, and if you'd like to argue that github means patches are less likely
to be abandoned that's a good argument to make.

I'm arguing for a broader look at what our development process problems
are, and that perhaps efforts should be directed elsewhere.
