Oh, pretty useful. I also couldn't find it on the wiki and this page

even claims it's going to be obsolete (starting with 7.10?).

Google shows that something related was mentioned in

but the new version of the page missed that info.

This emails refers to the no-longer available info on the wiki, too:

I wonder what happened and which info is meaningful only
for GHC < 7.8 or even ==7.8 and which parts make sense
for 7.10 as well.
