We only need to support 3 or 4 to get 99% of the stuff on Hackage that
lives in a VCS at all.

Perfect, meet better. Wait, no no - aw goddammit Perfect! Why do you
do this every single time? *You* get to mop the floor this time.

Not really. I do much the same thing locally. Most repos hardly ever change.
My own local repos - which includes all of patch-tag, a few GHCs, some
intermediate builds, and whatnot - is about 4.5G. By my calculations*
that's about 25¢ of hard-drive space.
