It's irrelevant, because I _do_ have root access to my machine, but
don't want to get forced into using it by a question that implies that
if you have access, you're going to use it. I didn't mean to nit pick,
though, I thought you were arguing for the other side...
I think the right question is "how many people prefer user installs
over system installs, wrt. their hackage packages?".
I estimate that, concerning developers, who are used to install
still-buggy, self-written libraries, as well as install things while
working, the percentage is very, very high: At least I don't want my
workflow to be broken to deal with the formal requirements of a global
install while developing, and I guess many others feel the same way.
Endusers, of course, might have other preferences, but cabal doesn't
(IMHO) cater to them, directly: It caters to distribution packages (or
windows installers, or whatever), so cabal's default behaviour is quite
irrelevant for those cases.
 Thinking of it... is there a way to tell cabal to pretend a package
is installed by giving the path to it's source directory? Just like
include directories, but with packages.
